Seems that installation could not set up right security permissons.
Do you have any security software or local\domain policy blocking this?
Can you do a verbose installation again , with msiexec options, and send the logs?
You may also want to take a look at the whole C: or C:\Program Files (x86) permissions inheritance, as well as your administrator permissons.
Anyway is the first time i have heard about this issue. You already solved the issue...unless it's happening to other computers.
