Abhimanyu Singh :
i cannot run some games on my laptop which runs under windows 8.1 64bit. now the problem is that the setup of the games says incompatible 16 bit application... so can i not change my windows to XP 32bit, to play those games?
I am not sure you can install a 32 bit windows on a 64 bit computer. You might want to check on that.
My suggestion here would be to install XP on virtual box or something like that.
Also, the application you are trying to run, try opening it with the vista compatibility.
Right click on your .exe file and
select properties, after that click on the
Compatibility tab and try playing with some options there. Unfortunately the lower youc an go is Vista, but it might worth trying.
