I receive this error when I try to install the latest version of DraftSight. The previous version had been removed already so I don't know why I should get this error during the install. I am using Vista 32 bit. I have cleaned the registry and updated the Windows Installer. I have also checked for malware, adware and other problems. There shouldn't be any problems installing DraftSight but it doesn't happen.

Any help would be greatly appreciated.
