I installed this program a while ago and it caused me no end of trouble. For some unknown reason the program puts a null value in the registry which can only be for clandestine reasons. I suspect it caused corruption in my registry as some 3rd party software programs can’t handle null keys. The key in question is “HKLM\Microsoft\Windows\CurrentVersion\System. The only way to delete a null key is by using RegDelNull.exe from sysinternals dot com. Its a command line program, therefore in a dos box type “(full path)\RegDelNull.exe -s”. You will be prompted with y/n to delete key.
