Based on the error screenshot supplied, the issue relates with no aamapi98.dll found under directory "C:\Connect-It\Connect-It Scenarios\sm94am95", so this has nothing to do with the amdb.ini file.

Looks like an adjustment is required for the proper path on any scenarios which can be accomplished via "Configure connector..." option (on right-click).

Either that or place a copy of the aamapi98.dll (from AM bin folder) into directory "C:\Connect-It\Connect-It Scenarios\sm94am95".  I would not recommend this.

Already, there is a copy of the aamapi98.dll in the directory "C:\Connect-It\Connect-It Scenarios\sm94am95".

So, what could be the issue? this DLL file is from AM bin folder

No clue what the issue could be.  I don't think the custom directory helps but I am sure there is a good reason to have it.  Hopefully there is a process to update this file in this custom directory whenever a new AM patch is installed.  Has anything else changed recently like security / access to this custom directory?  I can only assume something has changed else why would the error now start if that file was always there?

Do all the scenarios have the file copied to their individual custom folders or does that file in that directory coded in all other scenarios?

Nothing changed, also I tried to change the DLL file location, then use it and same issue happened

All the scenarios which are using this DLL file, have the same issue.
Also, this is the first time to use this file.

Any help, please?
