Answer 1

Download Itunes from Apple.com, not from within Itunes.
Redo the install, following the below procedure.   However, when you re-install Itunes,  right click and run the install as administrator.   For Win 7, you have to hold down the cntrl and shift keys when you right click and then "run as administrator" will be an option.
Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features (Vista, Win 7 & later)
Remove all of these items in the following order:
iTunes
Apple Software Update
Apple Mobile Device Support (if this won't uninstall move on to the next item)
Bonjour
Apple Application Support
Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.
The uninstall and reinstall process will preserve your iTunes library and settings, but ideally you would back up the library and your other important personal documents and data on a regular basis. See this user tip for a suggested technique.
Please note:
Some users may need to follow all the steps in whichever of the following support documents applies to their system. These include some additional manual file and folder deletions not mentioned above.
