Thanks alot, that did the trick for me also. I had this problem doing a fresh install (actually version 5.0.225) on two workstations (XP Pro SP2). I suspect that some of the system dll's are overwritten by the install. I haven't had the time to explore yet, but i suspect that overwriting oleaut32.dll and olepro.dll with older (pre SP2) versions, will cause problems. I hope that this will be fixed by KAV. I was lucky not to criple more than few WS in the attempt to evaluate the software.
