I have been into the registry and found the this key I do not have
permission to access it and after attempting to gain access I was still
continually denied. Any and all help would be appreciated. Thank you.
I had the same problem trying to load office 2007.
Go into the registry and find the key stated in the error code.
Right click on the key and click permissions. When the "do not have permission" prompt comes up just click OK and that should open the permissions box.
Click the advanced button (bottom right corner), owner tab, then under change name to, click on your pc and hit the apply button/OK. That should take you back to permissions. Now add your pc name, administrator, and system to the group and user names box, and check the full control and read boxes for each one. Now try the install again.
When I did my office install I had to do this 7 times for different reg keys.
It was very frustrating to say the least.
Good Luck hope this helps you.
