Hey Isaac, do you happen to know the format of the data base

From that forum post, it looks like the application does direct disk access, which means that just copying the files from the floppy disk isn't enough -- their location on the disk is important, too.
And if you can find the C source code for that application, it would greatly help someone port it. The author or current copyright-holder's permission to make it open source, under something like the GPL or BSD license, would be a real contribution to the community.
For a few dollars you can buy an old Windows 98 PC that will run DOS, I think there was one at the local salvation army store for $20. I happen to have one that I just never got rid of. I haven't turned it on in quite a while but the last time I did it worked great. It just seems like it would be easier to use DOS than to knock yourself out trying to work the bugs out of a DOS emulator.

Your link to the wayback machine works, but on that page, the link to the demo file doesn't work. I just tried it.
Edit - In case it helps anyone that wants to look into these issues, I've found a downloadable copy of a demo of the database (with only some of the relevant data and some of its functions) in the Wayback Machine's archive of Larry's website at the webage below
That would be my guess too.

Most likely, once you getting running, you'll only have something that allows you to view the data, not perform any type of export.
[Perhaps you could send us the relevant files and we could investigate the costs involved with hiring an expert to extract the data into a modern/open format. If it's not costly, we might be in a position to get it done, then make it freely available to anyone who wants it (assuming we can get permission to do so).

For what it's worth I'd open the .rnd and .vce file in a hex editor (UltraEdit, Emacs, Vim / XXD) to see if there are any text blobs that correspond to UFO cases. If it's not compressed, Larry's using simple serialization to encode the data. That's imminently more reversible than trying to figure out non-standardized compression algorithms and map out the various equivalence classes between compressed and uncompressed symbol sets.
" Larry Hatch's UFO Database is remarkable as a source of documentation which encompasses most of the existing compilations in a single, easily researchable file. As a research tool it clearly surpasses all previous efforts at cataloging carefully screened UFO data. And, the graphic and mapping facilities are simply superb. "- Jacques Vallee 23 NOV 1994

I have installed VMWare with Windows 95 on it. I've just tried the demo and it works well although many of the features have been taken out.

How big is the database in total mate?

Is there any possibility that the database may be on an embedded file that you may be able to access with a decompiler?
