Upgrade CiscoSecure ACS 3.3.3 to 4.1 fails

Upgrading CiscoSecure ACS 3.3.3 to

The existing installation was not removed correctly. Do you want to try again or abort this installation?

I hit Try Again and it comes back to same error.


Re: Upgrade CiscoSecure ACS 3.3.3 to 4.1 fails

It seems that acs files got corrupt. Make sure you have most recent acs config backup handy.

If you have 3.3 software , you need to go to support folder --->clean----> and run clean.exe.

It will clean all acs components. Now install it back and restore the database and try to upgrade it to 4.1.

Or remove acs setting from registry. Search for acs keyword and delete keys one by one.

Caution : Do it with great care as deleting any other key can cause system to crash. If you have good understanding of registry , then only proceed with it.

Or you can do this exercise on different system and install 4.1 fresh on current system. We need to keep and upgrade existing database that is why we need to follow these steps otherwise it is quite simple
