Hi, When I loaded Music Studio 10 it automatically went to "program files (x86)" which I believe for a 32bit OS. I'm running windows 10, 64bit. I'm also trying to get Band in a Box (64bit) 2019 and some VST2 plugins to be recognized by Acid 10 without any luck. Somehow I need to tell Acid to run in 64Bit mode. Big fan since Acid 1, 30 years ago? Any help, greatly appreciated. Thanks Chris.
