Can't install iTunes 10.5

[theipodkid]

Hi there,

I can't get the iTunes 10.5 to install as I get an error saying


'Could not open key;
UNknown\components\7ABFE44842C12B390AF18C3B9B1A1EE 8\000021599B0090400100000000F01FEC Verify you have sufficient access to that key or contact your support personnel.'

I can install other iTunes though like 10.3.1 but I can't update to IOS 5 using that one.

Thanks for any help
