Yes, you can run Unitronics software on Windows Vista, Windows 7 or windows 8.1.
We recommend for the user to run VisiLogic as an administrator and with UAC disabled.
You need to turn off the UAC before installing the software.
Please follow the guide on our forum below:

Running as an administrator can be accomplished by right clicking on the VisiLogic icon, choosing Properties, going to the Compatibility tab, and selecting the box labeled Run this program as an administrator.
