Are you sure the games you're trying are 32 bit and not 16 bit?
16 bit software are not supported in 64 bit Windows 8.
I have a GWBASIC interpreter of pre historic era that i tried to run 64 bit Windows 8.1, and I got the same message.
If the games are really 32 bit games, they should run. If not, try the compatibility mode and attempt running it in a previous version compatibility.
If its a 16 bit DOS era game, try installing "DOS BOX" and running it from there.
