It's not a matter of hardness. I was rather thinking that the install utility
HAS TO run on any system. Doesn't matter whether it's a machine with 8088 or
Pentium. Install should run gracefully on as small as 256KB of conventional
memory (I've seen some high-end computers with that much free!!).

I'm writing the code in ANSI C and using #ifdef's wherever compatibility
issues come into play. This way if there are any unvincible problems with TC
code, I can always move to DJGPP.

Well, it was just a suggestion... and not a very good one. ;-))
