How do I install and run TASverter?
After downloading the installation zip or tar file, unzip or untar the file into an appropriate directory on your machine. In the text below, the full path to this directory (including any drive letters on Windows and any trailing slash or backslash character) will be referred to as [TASverterDir].
NOTE: To avoid problems on Windows systems, make sure that neither [TASverterDir] nor any of its parent directories contain space characters in their names.
This release comes with two executables: TASverter.exe, which is the command line or batch application; and TASverterGUI.exe, which provides a graphical user interface for setting options and calling TASverter.

TASverter must be invoked from the command line. (On Windows you will need to open a DOS/cmd window: simply click on the "Start" button, select "Run" and then type "cmd")

At the prompt you might want to "cd" to your working directory. Then type:

This should give you the help text and demonstrates that TASverter is working.

Once you have verified that TASverter runs, you can update your environment to include [TASverterDir] in the command path.

On Windows you will need to "right-click" on "My Computer" icon on the desktop, or click on the "Start" button, select "Settings" and "Control Panel" and then open the "System" icon. Click on the "Environment Variables" under the "Advanced" tab. Click and edit the Path variable and set it to

On Unix systems, shell users will need to modify the appropriate .profile or .bashrc file, and add the following line:
export PATH=$PATH:[TASverterDir]
Once your environment has been updated to reflect you new command path, you should be able to run either TASverter or TASverterGUI by typing its name directly at the command prompt.

Even if you do not have access to the TASverterGUI, you should still be able to read the on-line help by pointing your standard browser at


I have a problem. What do I do now?
The installation procedure described above is somewhat generic, and there are a number of possible variations due to exact operating system versions or particular command shells. Please ask your system administrator to review the installation procedure above to see whether a variation applies to your system.

If you and your system administrator still have problems, please consult the list of Frequently Asked Questions because someone else may have already encountered your problem.

If you still have problems, please contact tasverter @
