Hi,

This question might be a challenge, so I hope somebody can help.
If this is posted in the wrong newsgroup, please let me know.

Many years ago (back in 1998), I built a game using Borland C++ Builder 1 
(It can be downloaded through ftp://ftp.vanderlee.com/pub/x98_12.exe, it was 
a christmas gift at the time).
The game still works fine on Windows 2000 and older OS versions, but 
starting WinXP, it doesn't.
The error I get at startup is "<exe> is not a valid Win32 program" (or 
equivalent in other language, I translated this from Dutch).
My own source-code and that of some 3rd party components I used did not age 
well, so recompilation would be a massive pain at best.
Even 9 years after release I still get people mailing me with questions on 
how to run this on XP/Vista, and I'd really like to provide them a solution.

Does anybody know what is causing this error?
Is it common for all BCB 1 compiled programs?
Is there a quick fix?
If not; is there a less quick fix?

kind regards,
Martijn
