Does ForScore run on Windows Vista and Windows 7?

Yes, version 2.0 has been running under Vista since March, 2007.
If your license is on a dongle, you may need to download new drivers for 64-bit Vista or for Windows 7 from the download page.

More information is in the ForScore documentation.

There are some potential issues with Vista's DEP (Data Execution Prevention). Contact Beach Bunny Software technical support if you encounter them.
