Resolved iTunes 8.2.1 problems

Just downloaded and tried to install iTunes 8.2.1. It failed with Service "Ipod service" could not be installed. Verify you have sufficient privileges to install system services.

I am logged on as Administrator and previously successfully installed version 8.2.0 without a hitch. I tried installing in Safe mode but it wouldn't even start - error "The administrator has set policies to prevent this installation ".

Currently I have iTunes running but am unable to use iPod with it.

(Windows XP2 SP2).

Any suggestions very welcome.

 

Solved.

Fixed it.

For anyone else having problems :-

Disabled firewall (Online Armor) & Antivirus (Avira Personal) and then it installed successfully. Don't know which one caused the problem.

BTW You can't install in Safe Mode because you can't run Windows installer (I think).
