I've tried it on Win98, run without problems. They say that the 32-bit Windows version run with all versions of Windows. The only problem was with control panel applet under WIN95, but fixed now.

If you want to try the server, download this admin tool, the personal edition of IBExpert, is freeware :

>>You should try FirebirdSQL too. It is a very small database server (only 2.7 MB download) and is based on Interbase code. It has native windows compiled binary with installer, is fast and has many features (stored procedures, triggers, transactions, referential integrity, etc). You will find a lot of admin tools for windows, drivers, ole db and .NET provider. Check www.ibphoenix.com and www.firebirdsql.org

>It certainly looks interesting. Do you know what versions of Windows are supported? In one place it mentions Windows NT, in another place, "32-bit Windows". (I am currently using Windows 98.)
