Error 1335

Hello.

I'm running Win XP Pro SP3.
AVG Internet Security 9.0 (All except firewall turned off).

When I try to install Virtual PC 2007 I get error:

Error 1335. The cabinet file 'product.cab' required for this installation is
corrupt and cannot be used...

I've tried downloading it three times with the same result each time.

Any help please?
