I upgrade ACS from 4.1.4 to 4.2. I need to downgrade back to 4.1.4 without reinstalling W2003 server! But when I remove 4.2 I could not reinstall 4.1.4 because of "4.1.4 must be installed only on top of 4.1.1.x or 4.1.3.x". Using Clean.exe utility does not solve it. Cleaning registry does not solve it. I tried to watch "what was going behind" (find relevant lock file or register) using programs like FileMon anf RegMon, but without success. Thanks for any help in advance. RJ
If you have the ACS 4.2 CD there is a support folder -> clean -> clean.exe. If you run this utility it will completely remove ACS from your system. If you do not have the ACS 4.2 CD please open a TAC case if you have a contract and we can provide the media for you. The clean utiltity if version specific so you will need to 4.2 CD to remove the 4.2 install.
