Just upgraded my motherboard\CPU and RAM, now Vegas Pro 12.0 (64-bit) won't start. I usually start it w/administrator privileges (it acts like Quicktime isn't installed if I don't). Trying with or without admin it does nothing. It's not listed in task manager or anything. Production Assistant starts just fine, and no other software is misbehaving. I double checked and the folder with all the files is still there. Not sure what to do at this point. Anyone have any ideas?
