Easiest fix: disable Protected Mode.
OR use Windows 7 OR Acrobat Reader v10.1.4 OR not run as administrator. Is this the appropriate venue to report this bug to the Adobe developers?
No, this is a user forum. I'm sure the developers have known for a long time that Protected Mode is hopelessly broken, but so far there is no indication that they are ever going to fix it. Disabling Protected Mode is a recommendation that I make about a dozen times every day in this forum.
