Whenever I click a hyperlink on any of my 2010 Word documents I get the message "This operation has been canceled due to restrictions in effect on this computer. Please contact your system administrator." Well, I am the administrator of my computer and I don't know what to do to resolve this issue. Help!

Right click on the Word icon and select "Run as Administrator" from the menu.

Also try Microsoft FixIT utility
