Nemetex FAQs

2. I can't download the program. I click on the "Accept License Agreement and Download" and get a screen stating "The website declined to show this webpage" [or similar].

After clicking on "Accept License Agreement and Download", there should be no other barriers to downloading. The most probable cause for inability to download at this point is a barrier at the user-end such as a restrictive PC or network firewall setting. Please adjust your PC's firewall settings to allow the download, or contact your network administrator if the restriction exists at the network level. If this does not solve the problem, contact us at info@accessisoft.com and we can send you a CD with the program setup file and evaluation license key.

3. I successfully loaded Nemetex on my computer, but it won't start from the icon or from the start menu; or the only thing that happens is a blank black window appears briefly, then disappears.

The most likely cause is that the version of Java Runtime Environment (RTE) installed on the host computer is not at least J2SE 1.5.0_10 or later. The Java web site contains an on-line version verification tool which can be used to determine if the most current version of Java RTE is installed and update it if needed.

Also note, the first time Nemetex is run after initial installation, or after installing a new version of Java RTE, it will take up to a minute to open while Nemetex examines the Java files on your computer and copies any additional required files into the Java folder.

4. I downloaded the program file, but can't run "setup.exe."

The most likely cause is that the user does not have sufficient permission to run set-up files and thus install programs on the host computer. If trying to install the program on a stand-alone computer, verify that the user profile being used to install the program has "administrator" or "full" rights. If trying to install Nemetex on a network computer, contact your network administrator or technical support representative.

The installing User having administrator rights is vital if installing Nemetex Nemeth Back-Translatorä on a Windows Vista^® or Windows^® 7 computer. If a User with administrator rights still is prohibited from installing Nemetex on a Windows Vista^® or Windows^® 7 computer, turn off User Access Control (UAC) to complete the installation. UAC can be turned off or on from the User Control Module within the Control Panel.

5. I received the Nemetex license key AccessiSoft sent me and tried to open it, but my computer could not open it.

Both the evaluation and commercial license key files sent via e-mail by AccessiSoft neither contain the program nor can they be opened by your PC. The license key file contains encrypted codes which the Nemetex program will read and allow the program to be opened and used. The file containing the program itself needs to be downloaded from www.accessisoft.com and installed before adding the license key. When you receive the license key, save it into the folder on your computer containing the program (normally "C:\Program Files\Nemetex" or "C:\Program Files (x86)\Nemetex" for 64-bit Windows Vista^® or Windows^® 7). If you are trying to save a commercial license purchased after you successfully evaluated Nemetex, it is likely your computer will ask you if you want to replace the existing file "C:\Program Files\Nemetex\license.key" (or "C:\Program Files (x86)\Nemetex\license.key" for 64-bit Windows Vista^® or Windows^® 7). If so, check Yes. If the program still does not open, see Question #3 above or contact us at tech.support@accessisoft.com.

6. I have been running Nemetex with no problems, but now it asks me for a new license key.

If using an evaluation version, your evaluation license key probably expired or is for an older version of Nemetex (Version 2.3 was posted to our web site for download on 1/1/09).

If you found the evaluation copy of Nemetex met your needs, click here to purchase a full permanent version of Nemetex.

If you need a little more time to determine if Nemetex is right for you, or are trying to use an evaluation license key issued before 1/1/09 with the current program version, request another 30-Day Evaluation License using the form on the bottom of the Contact Us page. The new evaluation license key will be sent via e-mail to the e-mail address you provide.

If you recently re-built or re-organized your computer's files, the license key may have been moved to a location other than the folder containing the program or lost all together. Search the computer (normally "C: Drive") for a file called "Nemetex.key." If you find it, move it to the folder containing the program (normally "C:\Program Files\Nemetex" or "C:\Program Files (x86)\Nemetex" for 64-bit Windows Vista^® or Windows^® 7), or when prompted to specify the location of the license key by Nemetex, browse for the correct location. When Nemetex finds it, it will write a copy to the same folder in which it resides to alleviate this problem in the future.

If you lose or cannot locate the license key file, please contact us at tech.support@accessisoft.com to request a new license key file be sent via e-mail. We recommend you include the license key in the back-up copy you make of the program.

7. I'm running Windows Vista^Ò or Windows^Ò 7 and get a warning stating that Nemetex cannot write to Program Files after I told the program where it can find my new license key.

The first time you try to run a new installation of Nemetex, the program will ask you to specify the location of the license key sent to you by AccessiSoft so that the program can retrieve it. Once retrieved, Nemetex stores a copy of it for future use in "C:\Program Files\Nemetex" or "C:\Program Files (x86)\Nemetex" for 64-bit Windows Vista^® or Windows^® 7. The safeguards associated with the security modules in Windows Vista^® and Windows^® 7 perceive this act as potentially malicious and, if your computer is set to maximum security, it will prevent Nemetex from saving your license key and will give you a warning stating such.

In order to prevent this, turn-off User Access Control (UAC) (if not already turned off) to allow Nemetex to properly store your new license key for future use upon start-up. Do so by entering the Control Panel via the Start-up Menu, selecting "User Accounts and Family Safety", then "User Accounts." Note that if you have the Control Panel set-up for the Classic View, you can select "User Accounts" directly. Then uncheck the box next to "Turn User Account Control On or Off." Finally, restart your computer to effect the change in UAC status.

Once Nemetex is up and running, if desired, turn UAC (for Windows Vista^® or Windows^® 7) back on by performing these steps again, but this time by leaving the check box checked instead of unchecked.

8. Nemetex does not seem to work properly with JAWS^Ò for Windows^Ò or Window-Eyes™.

While a screen reader is not required, the Nemetex Nemeth Back-Translatorä has been tested to be compatible with Window-Eyes™ and JAWS^Ò for Windows^Ò. Appropriate interface software must be installed to ensure the screen reader works correctly with Javaä. At this time, available interface software runs correctly in 32-bit operating systems only. Click here for procedures from Microsoft to determine if your operating system is 32-bit or 64-bit.

If JAWS^Ò for Windows^Ò is to be used, the Javaä Access Bridge For Windows Operating System interface software must be installed (available for 32-bit operating systems only). It is available for free download from http://java.sun.com/products/accessbridge/. The Javaä Access Bridge For Windows Operating System must be installed, or re-installed if previously installed, after installing the latest version of Java RTE as discussed in Question #3 above.

If Window-eyes™ is to be used with Nemetex, interface software must also be installed. WE4Java 0.9.19 by Jay Macarty is the recommended application to be installed (available for 32-bit operating systems only). It can be found for free download from GW Micro Script Central at http://www.gwmicro.com/Script_Central/Scripts/Script_Details/?scriptid=1222 (install the most recent version). WE4Java must be installed, or re-installed if previously installed, after installing the latest version of Java RTE as discussed in Question #3 above.

9. Does Nemetex convert LaTeX to Nemeth?

Nemetex Nemeth Back-Translatorä does not convert LaTeX to Nemeth. There are other products available from various sources which convert various forms of printed math, especially LaTeX to Nemeth. Nemetex was developed to tackle the challenging problem of converting Nemeth code embedded in a file also containing standard text (in Grade II Braille) to LaTeX so that the document can be further propagated to other sighted math users or printed-out on standard paper.

For example, I do all my math homework on my BrailleNote, machine-translate the file as a text file (.txt"), then export the file to my computer (also see Questions #11 & 12 below). I then use Nemetex to back-translate the file into LaTeX and save it as a ".tex" file. I compile it in a LaTeX editing program (TeXnicCenter or Scientific Notebook) and print the finished product to turn in to my math teacher. The term "back-translate" is used throughout the visually-impaired math education community for this process because, for many years, there have been products available to "forward-translate" some from of electronic math into Nemeth Braille for student use.

10. My Braille Notetaker has a QWERTY keyboard. Will Nemetex work with my math files?

Nemetex will work with most QWERTY Braille Notetakers provided it has a six-key entry mode and that mode is used to create the original file by one of the methods discussed in the User's Guide.

11. What do I do after Nemetex converts my Nemeth to LaTeX?

The final output of the Nemetex Nemeth Back-Translatorä program is a .tex file which is then readable by any standard LaTeX-based publishing software program such as TeXnicCenter (see http://www.artofproblemsolving.com/Wiki/index.php/LaTeX:About for information about downloading both TeXnicCenter and MiKTex) or Scientific Notebook (http://www.mackichan.com/). After Nemetex converts the file to LaTeX, it is best to save it as a ".tex" file in a convenient location on your computer, then open or paste it (depending on the program in use) into the LaTeX program.

If the desired final output file format is .PDF, a free .PDF reader program can be downloaded from http://www.adobe.com/products/acrobat/readstep2.html. Other readers may be available and/or required to view final output files from other LaTeX-based publishing software programs (i.e., Scientific Viewer for Scientific Notebook).

Please refer to the Nemetex back-translation process Flow Chart or Nemetex User's Guide for more information.

12. After creating my file containing Grade II text and Nemeth Code Braille, I saved it, transferred it to my PC and changed the file extension to ".txt". When I tried to run it through Nemetex, it was garbled or had other back-translation errors.

Simply changing the file extension of a Braille file from something like ".brf" to ".txt" will not effect the necessary changes to the file which allow Nemetex to properly back-translate the file. Prior to transferring the file from the Braille Notetaker to the PC containing Nemetex, the file should be machine-translated on the Braille Notetaker to ".txt" format. This will ensure the correct conversion of the text from Grade 2 Braille format to ASCII.

Please refer to the Nemetex back-translation process Flow Chart or Nemetex User's Guide for more information.

13. Why does Nemetex crash when I try to translate my file?

If Nemetex crashes (stops translating and closes) during translation, the most likely cause is a significant error in the original Braille input file format or content. Errors are most likely to have originated in the Nemeth Braille Code itself or in file preparation. If the program stops and exits during translation, please refer to the File Preparation Methods in the User's Guide and then carefully proofread the original Braille file.

If the error cannot be found by proofreading, consider breaking-up the original Braille Input file into segments and translating each separately until one fails to translate. This will help isolate the fault and provide a portion of the file in which to focus further proofing.

14. Does Nemetex work on my new Windows Vista^® PC?

Nemetex Version 2.3 is compatible with Windows Vista^® and Windows^® 7. If you have been using an older version of Nemetex, and you upgrade your operating system, or want to use Nemetex on your new Windows Vista^® or Windows^® 7 PC, download and install Version 2.3. If you purchased an older version of Nemetex in 2007 or 2008, you were automatically provided a new Version 2.3 license key for use in upgrading versions. If you have been evaluating an older version of Nemetex using Windows^® XP^®, and wish to continue evaluating it using Windows Vista^® or Windows^® 7, request a new Version 2.3 evaluation license key via our Contact Us page.

However, the Java^® Access Bridge For Windows Operating System, which must be installed to allow JAWS^® for Windows^® to be used with Nemetex, is only currently available for 32-bit operating systems. So if your computer has the 64-bit version of MS Windows XP or MS Vista operating systems installed, Nemetex will run properly, but will not be fully screen-readable by screen readers such as JAWS^® for Windows^® or NVDA (please refer to the next FAQ).

[Back to Top]

15. I'm visually-impaired and used a screen reader to install Nemetex, but then it won't properly read Nemetex when I try to run the program.

Unfortunately, at this time, interface software applications necessary to allow screen readers to work correctly with Java™ are only available for 32-bit operating systems.

Java^® Access Bridge For Windows Operating System interface software must be installed to allow JAWS^® for Windows^® to be used with Nemetex. Interface software must also be used with Window-Eyes™. WE4Java 0.9.19 interface software by Jay Macarty interface software is the recommended version to be installed to allow Window-Eyes™ to be used with Nemetex. So if your computer has the 64-bit version of MS Windows XP, MS Vista^®, or MS Windows^® 7 operating systems installed, Nemetex will run properly, but will not be fully screen-readable by screen readers such as JAWS^® for Windows^® or Window-Eyes™.

Options include: (a) Having a sighted assistant run Nemetex for you; (b) using Nemetex on a different computer with a 32-bit operating system installed; (c) restoring your operating system to a 32-bit operating system; or (d) setting-up a Virtual PC (separate partition) on your 64-bit computer in which you run a 32-bit operating system. This last option will incur additional cost because it will require you to purchase another copy of a 32-bit operating system. While time-consuming, we definitely know this last method will work because we demonstrated it on a new laptop that came with 64-bit Windows Vista^®.

16. What happens to my data files when I uninstall Nemetex?

Nemetex is not configured by default to store your translated files in the "Nemetex" folder (normally "C:\Program Files\Nemetex" or "C:\Program Files (x86)\Nemetex" for 64-bit Windows Vista^® or Windows^® 7), which is removed during the uninstall process. The default directory for the "Open", "Save" or "Save As" dialogue boxes is the current User's "My Documents" folder. So, translated files would not normally be deleted during the uninstall process.

However, during Save or Open processes, you may have changed the target location of your translated files, and may even have chosen to make this new location the new default file location using the Translation Options. Translated files stored in any location other than the "Nemetex" folder (normally "C:\Program Files\Nemetex" or "C:\Program Files (x86)\Nemetex" for 64-bit Windows Vista^® or Windows^® 7) will not be deleted during the uninstall process.

17. What's new in Version 2.2?

Version 2.2 of the main program was released October 5, 2007. It is significantly easier to install by being packaged as an Application file (.EXE) vice a Zip file and thus can be installed directly from this web site or after the set-up file is copied to your computer. It also adds many new supported symbols and supports additional layers of fractions. In addition, minor anomalies reported by evaluation users were corrected. The default settings for the Translation Options "Number of Paragraphs to Skip at the Beginning of a Document" and the "Number of Paragraphs to Center at the Beginning of a Document" were also changed from two to zero.

18. What's new in Version 2.3?

Version 2.3 of the main program was released January 1, 2009. It has been tested to be fully-compatible with Windows Vista^® and Windows^® 7, both 32-bit and 64-bit versions (accessible using screen readers on in 32-bit operating systems). It also adds several new supported symbols and corrects minor anomalies reported by users. Additionally, an installation anomaly was corrected which greatly simplifies the process for installing a new license key (evaluation or permanent) after an old evaluation license key expires.

[Back to Top]

19. What's new in Version 2.3 Updates 1 and 2?

Update 2 to Version 2.3 of the main program was released March 27, 2010. It has been tested to be fully-compatible with Windows Vista^® and Windows^® 7, both 32-bit and 64-bit versions (Nemetex is fully accessible using screen readers in 32-bit operating systems only). Update 1 adds 13 new supported symbols; enhances error recognition and reporting by adding an error report file citing errors produced upon completion of translation; enhances compatibility with Scientific Notebook (http://www.mackichan.com/); and generally streamlines portions of the software to speed the translation process on older computers. Update 2 incorporates some user feedback, corrects one anomaly, and further enhances compatibility with other accessibility software, such as Duxbury Braille Translator for Windows. Update 2 to Version 2.3 uses the same license key as Version 2.3, so no new license key is required for holders of a permanent version 2.3 license key.
