Re: Program hangs at start...
OK, I have installed Vegas Pro 11. The instructions you were sent only refer to the program install when they suggest going to the Program files folder (for x64 install) and deleting the folders in the Sony folder. Note, they do not mean the Program Files (x86) folder unless you might be running a 32 bit version of Windows 7. They say Sony Setup folder, but I do not see one of those. I have no, however, set any preferences in the program.
The rest of the instructions involve using an administrative account. If you receive a UAC prompt when you start the install, I don't really see why, but you can do that if you choose.
If there is anything about the way you installed, or some type of project you were running, or anything else that might help me duplicate your situation, please advise. I will be playing with the software for a while, until you post back.
