“insufficient privileges” errors when installing iTunes 10.0 (Bonjour)

I attempted to install iTunes 10.0. Initially I used the auto-installer and I received the following errors:

"The installer has insufficient privileges to access this directory: C:\Program Files\Bonjour. The installation cannot continue. Log on as administrator or contact your system administrator."

Then the same error with the following file:

"C: \Program Files\Common Files\Apple\Mobile Device Support\com.yahoo.go.sync.client.resources\...\Windows."

I was given two options to either "retry" or "cancel" --"retry" just keeps throwing the error up. I was forced to click "cancel" both times.

Following hitting cancel twice I got an "installation interrupted" message telling me that the installation had failed.

Following the errors recommendation, I logged off and relogged on as the administrator. Then I downloaded iTunes 10.0 from the Apple web site and attempted to install it manually as the administrator while logged on as the administrator (right click the program "run as Administrator"). I received all the same errors and the same failed installation.

When I attempt to go into the program files and alter the privileges to bonjour or the Apple\mobile device support I get a “you do not have permission to view or edit this object’s permission settings” even when logged on as the administrator. It appears that both are Apple programs probably installed with a previous version of iTunes so I am not too sure why the tight security and why I do not have the ability to modify them.

I am running Windows 7 (32bit). Any assistance with getting iTunes 10.0 installed correctly would be greatly appreciated.
