[THIS ISSUE HAS BEEN SOLVED REFER TO BOTTOM POST BY OP]. ======================================== My beta expired so I used CODY's office tool to uninstall the beta. I restarted and tried to install the trial but I get this error. I read then that I was to delete the following reg entries Problem is the bottom entry is not deleteable. If I try to delete it or a subfolder or the key I get I am running Win 7 Pro x64. I would greatly appreciate any help so I can clean this and install the office 2010 trial.
