Big problem with this. I have it working fine on my old PC with Windows 10 32 bit, using Overture 3.5 SE and hosting the GPO instruments in Garritan Studio v2. I'm migrating everything to a new machine with W10 64 bit, and I can't install Garritan successfully, so now unable to access the instruments. I've been advised to upgrade to Overture 4, which I've done, and to use the VST plugin option, but I can't get Overture to recognise any VST plugins. Can anyone please help with this?
