Norton SystemWorks Basic Edition

I have Norton SystemWorks Basic Edition installed on my PC.  After upgradings Windows Vista x64 to Windows 7 the other day I decided I want to uninstall SystemWorks.  However, whenever I try to run the uninstaller from Programs and Files I get an error message that the programis incompatitble with Windows 7 and closes.

 

Is there a way to manually uninstall SystemWorks from the computer?
