If you want to install the OmniPass software version which was designed for Windows Vista in Windows 7 think twice before making this mistake. Doing so can result in a very long delays during the logon of the user’s profile who installed the software. This can even cause some of your user profiles to be unable to login constantly showing the “Welcome” message on the screen.
So do not install the OmniPass software (the version which was designed for Vista) in Windows 7 if you want to have your system to be usable.
