[GNC] Help please. Upgraded from 2.3.4 to 4.12. Worked fine. But database does not load. Win 11.

[Maf. King]

Just an observation, from the depths of history...

IIRC, 2.3.x I think was a development series; unstable and for bug testing and 
so on, and for "expert" users only  (ie not me)

it feels to me that having that running on win11 is unlikely, I'm not even 
sure that 2.3 release were for windows - if they were available then they 
would have been some of the very first releases of GC on winXP. 

I am pretty sure that if 2.3.4 was installed by the OP, then the GC database 
would be in XML not SQL and so the usually auto-created backup files should 
have been made and might be lurking in a corner of a hard disk?

HTH,
Maf.
