How can I disable access denied when copying from network drive to program files?
Disabling UAC is not enough.
You need to disable Admin Approval Mode (requires restart). More details here (option B, last screen shot): http://www.petri.co.il/disable-uac-in-windows-7.htm
This worked for me and now I can work w/ files and folders from Program Files w/o any more UAC prompts.
