This thread explains how to use Tk with Vizard
Step 1:
Download the following file to your computer:
tkinter.zip
Step 2:
Open the file with Winzip or a similar program. Extract the contents of the zip file to
[VIZARD_PATH]\bin\ where
[VIZARD_PATH] is the location of your Vizard installation (usually
C:\Program Files\Vizard).
That's it, Tk should now work with Vizard. If you have any problems please post them here.
