Have been running Slimserver 6.5.4 without a glitch on XP SP2 for about 3 weeks now.
When installing Vista on a new Dell for a friend , I decided to give it a try on that OS.
Gave up after a couple of hours - reading and applying all known Vista fixes.
Also disabled all possible interfering programs ( Windows firewall, ZoneAlarm, AVAST antivirus )
From windows services the slim service always appeared "starting", never "running".

Reality is that starting slim.exe from dos box the following error message appears :

PS. Thanks for a very nice product ( at least under XP ) and keep up the good work.
