Are your other mods working? Is this a specific problem you have with 1648? Have you been able to play 1648 before?
I will copy and post the offline launcher and configuration files from my gaming computer (which should be corruption free) later tonight when I am back home. If you only have a problem with 1648, you could try to run the mod by using those.

Not recently.
As far as I can tell the kingdoms.exe itself works, at least after I replaced it from a copy that was working fine. SS, BC and the original Kingdoms mods (Crusaders, Americas, etc) also do not run but two kingdoms mods that I have not played in years (Rusichi and Chivalry II), do actually run. That is mysterious. The missing desktop shortcuts (SS setup and 1648 Reichsmutation) were restored by restoring to my 1st of February restore point, so these probably went missing after the critical update. I will run Geomod on the various non-working mods, just in case it shows anything.
Unless Geomod reports some issue, I may have to reinstall everything from the medieval II disc, downloads and backups and then hope that critical update has not permanently messed something up. I am not looking forward to that.
