Hi, thanks in advance if you can, I am unable to install Windows XP SP2 on my Windows XP Home Retail with SP1a installed OS. The error message is "Service Pack 2 Setup Error - Failed to install catalog files. Select 'ok' to undo the changes that have been made" From googling I have tried deleting and renaming the catroot2 file in c:windows/system32, I have looked through Hijackthis and can see nothing out of place have also used fixwareout and done a full virus scan with AVG free 8.0, I have also been told to make sure my cryptographic services is started but all to no avail. If anyone is able to offer me assistance with this I would be eternally greatful. If you require any further info to hesitate to ask. Thanks once again. Chris
