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

[john]

The oldest release still on SourceForge is 2.2.0 and it includes a Windows setup.exe; the oldest unstable release is 2.3.0 and it does not, but all from 2.3.2 do have a setup.exe.
The first commit to gnucash-on-windows was on 25 August 2006, not quite a year before, and the first announcement of a setup.exe being available is for 2.1.1 on 28 April 2007.

Regards,
John Ralls
