Ok, I didn't find such an old binary.

Does anyone still have such a binary running, or a Windows 2.0.x exe somewhere?

Actually, this quite a bit easier than I expected. I downloaded the
Windows 2.2.9 binary and opened the newer file and saved it, then 3.10
could open it successfully. :)

Can you please fix this warning:

"This file/URL appears to be from a newer version of GnuCash. You must upgrade your version of GnuCash to work with this data."

that appeared for this file?
