oh I think I figured it out... if anyone is interested.
I used the 16 bit setup in windows 64 bit option.....

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows...

I had one of those, I think it was a Cyrix

My question is: how do I make windows run a program when it knows its a 16 bit app on a 64 bit PC.
I know it reads the exe pe header, but instead of displaying the "This app cant't run on your PC"...
