W2000+latest securitypack The message appeared during installation. At first I was doing an upgrade to 4.5 that ended in failure. Rebooted and clicked a fresh download of 4.5, same message and repeated itself ten times till I deleted the dll. Problems now solved. Dlls got corrupted. Running 4.5.523
I,m sorry for letting the alarm go off. The problem is solved. The dll's got corrupted, why I do not know. Sending the setup log.
