Hello,
Sorry to hear you are having trouble.
You can delete the files manually from where you have them installed, likely:
C:\Program Files (x86)
and perhaps in \Stardock or \[TheGameNam]
To get it out of add/remove programs, you can see if it's here in the registry and delete it:
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\
