Greetings, Just upgraded my home PC from Win98Se to Win2K+SP2 (I wiped the disk first, so it's effectively a fresh install). I installed TDS-3 using Administrator login, and it runs fine while logged in as Administrator. However when I login as a non-administrator (a poweruser in this case) the execution protection won't install - actually it says it's installed okay but also throws an error window. My guess is some sort of file move/copy is failing. I've temporarily given powerusers full control over my TDS-3 directory and all sub-directories & files, and also over the C:\WINNT\inf directory as it appears to install some files there when installing execution protection. However this does not fix it. Anybody got any ideas what might be causing it ? I'm pretty sure it a permissions-related problem because if I change a poweruser to administrator group then it installs. I thought the inf directory perms would solve it, but maybe there is another directory somewhere that is also used ? Regards. Pitbull.
