Technically, Firebird 1.5 is not compatible with Windows 10, iirc it
hasn't even been compatible with Windows Vista. However I do know
Firebird 1.5 can run on Windows 10, but for example the local protocol
doesn't work. I suggest you try 1.5.6 first (I don't really understand
why you are still three point-release behind the latest 1.5; 1.5.3 was
released in 2005, 1.5.6 in 2009). However I expect that the 1.5.6
installer won't work either. The alternative is to try to use the zipkit

That is: manually install Firebird from a zip archive, and register
services and client DLL manually as necessary using instsvc and

And you could always try to use a VM with an earlier windows version to
run Firebird.

Please consult the release notes of Firebird 2.0, 2.1 and 2.5 for
compatible changes. However, I suggest that if you are in panic

I suggest you don't jump and upgrade to Firebird 2.5 in panic, but try
the zipkit first, and then when things have settled down, you should
investigate upgrading to Firebird 3 (or 2.5), and carefully test your
application. However don't do this in a rush. There were a number of
breaking changes (some of them subtle!) between 1.5 and 2.0.

Good luck,
