iTunes Update: Installer has Insufficient Privileges
"The installer has insufficient privileges to access this directory. C:\ProgramData\Microsoft\Windows\Start\Menu\Programs\iTunes. The installer cannot continue. Log on as administrator or contact your system administrator."
System specs: Windows 7, x32 or x64, fully patched & SP'd
I just worked with my cousin in Colorado over Skype to get this resolved. This is a fairly obscure error, and if you try to edit the permissions of the folder, run the installer as an administrator, log on as an administrator and run it, no actions seemed to resolve the problem. We did get it fixed, which involved the following steps. Not all of these may be strictly required, but hey, it worked for me. ;-)
1. Download the latest iTunes installer
2. Rt. click the installer, select 'Properties'
3. Click on 'Unblock', then click Apply, then OK.
4. Click on the Windows icon and type 'uac' (no quotes)
5. Click on 'Change User Account Control Settings'
6. Move the slider down to 'Never Notify' (NOTE: This will require a reboot)
7. Rt. click the installer and select 'Run as administrator' from the context menu
8. Let the installer complete (it should now)
9. Open 'Change User Account Control Settings'
10. Return the slider to the position you found it on (likely 2nd from the top)
Hopefully this helps you resolve this issue. All the best, iTuners!
