I too am getting this error message:
"This operation has been canceled due to restictions on this computer"


This followed a deep clean - much needed - of my registry.

I'm using VISTA & Office 2007. The file detailed below doesn't exist. Any other suggestions?

"Go to HKEY_CURRENT_USER\Software\Policies\Microsoft\Inte
rnet Explorer\Control Panel

Change value of "Homepage" from 1 to 0.
