Admin account does not have permission to install Itunes

I have administrator rights on my Windows 7 account, and I always have problems installing programs. Usually it is with a folder called config.msi. I don't have write permission for that folder and when I install anything I get multiple error messages about it.

I have been unable to install the latest Itunes, and I tried to install it manually. Everything went fine, except for the usuall config.msi errors, until the final part of the install. It said it did not have permission to access the itunes folder in program files. I looked at the properties of the folder, and I did not have write permission. The Itunes installer undid the entire install and deleted the itunes folder.

When I go to the program files folder, I do not have write access to it, and I cannot change it. I followed the instructions in this forum to enable the administrator account, and could not get write access to that folder from administrator either.

The error messages I get look like there is another account out there that is a superuser. Is there any cure for this?

There are other files and pointers in my system such as a shortcut to my documents, that I do not have permission to use. I click on them and get an error message.
