I am trying to upgrade a user to Adobe Acrobat reader 9.1. She currently has Adobe Acrobat Standard 6.0 installed on her PC running Windows XP Professional SP3. The install process goes smoothly almost to the end. Then the process stops with the Error 1402, which says the users does not have access to a registry key. It have made sure the account does have access to the key manually using regedit and I am using the Domian Admin account to do this installation. I have installed Adobe reader 8.0 (which works fine) as a temporary work around but I would like to slove this now.
