ABC2Win is a Visual Basic Runtime program, and requires a "VB Runtime" core that was so commonly on the majority of older systems that it was left out of the download. WinXP uses very little VB programming, if any, and there are apparently not enough VB programs out for XP to give a good likelihood that you'll have the necessary runtime components installed.

I made a brief stab at chasing down components, and most of them seem to be available; but short of recompiling with the runtime core included (masssively bloated file size for download) there were just too many missing bits and pieces. I gave up.

The necessary pieces are probably on your, or my, older Win98 machine. It's just a problem of finding the right ones and getting them moved.

It's possible there is, or will eventually be, an update of ABC2Win to address this. I don't use it often enough to fight with it now.
