The installation instructions don't cover this. I'm trying to install Tor Bundle for the first time and the setup prompts me for an installation location, defaulted to a folder on my desktop. This doesn't seem right and I don't want to proceed without confirming.

But if I change it to c:\Program Files\Tor Browser or c:\Program Files (x86)\Tor Browser and try to proceed, I get this error:

Perhaps this is due to UAC? I'm not prompted. I don't know if running the install As Administrator is the right thing to do either.
