Vista Does Not Support Older Help Files?

Today I installed a few freeware PC games on a Vista laptop. One of the games was a bit obscure, so we selected the “help” button. We did not get help.

We got a Microsoft message saying Vista does not support the format for the help file. I did not chase it, so I can’t say if this was a Windows 95 or Windows 98 or Windows ME or Windows 98 SE or Windows 2000 or Windows XP help file.

Why should I care?

Vista runs the game OK, but Vista no worky with the associated help file.

That’s no way to run an Air Force.
