I had this program on an older PC and it was fantastic, but my current PC is a 64bit quad-core on Windows 7 Pro. Will the current version of Guitar Power run on this operating system?
Yes, the current version of the software is working just fine on Windows 7 64bit. I've installed it and then the software was launched correctly. I even started playing the available notes and demos.
