I set up WinXP with a clean install for 5 users. Worked great on 2 accounts, in setting up the 3rd account I get the following error. Error: Access violation at 0x7350B307 (tried to read from 0x031001A0), program terminated or something with very similar numbers. It happens on startup when I have Spybot running, or without spybot running it happens when I click enable protection. It runs just fine on the first 2 accounts that I set up. So I don't think I'm missing files or anything. Thanks for any advice.
