Q: Now the problem occur when uninstalling Matlab 7 from Windows 7. When
trying to uninstall Matlab 7 a message "exception calling main" shows up
and stop the uninstall process.
A: Basically you just need to change the Windows 7 theme to Windows Classic and the uninstall program will run just fine. So if you don't know how to change the Windows 7 theme, here is the instruction:
1. Right click at the desktop > click personalize > Scroll down
to the bottom of the window screen > click Windows Classic. 2. Now uninstall Matlab 7. Click Start > Matlab7 > Uninstall.
