Ok, I usually use DOSBox to play PoP1 and other DOS games, i'll try to install Windows 3.1 with it.It is possible to install Windows 3.1 within DOSBox.
I tried to enable Windows 95/98/XP compatibility, but i guess that i should enable 16 bits compatibility, which i don't see that option in Windows 8, 64 bits.
I think i'll keep using DOSBox for that. Thanks
