w95 games almost certainly won't run
w98 may run (you need to try ... there are no hard rules)
if no joy try compatibility mode ... right click the exe file and try compatibility .... newest first ie 98, 95
the only certain way is to d/l virtual PC

it's free - install 95 or 98 .... then install the progs you want to run.
I have wordstar, lotus 123 ... wolfenstein ... all running on various virtual PCs
