Prince of Persia for PC Windows 7 [closed]

Do you mean that the 1989 game Prince of Persia failed to run?

I do not think there are multiple versions of this game for PC out there. This is a 16-bit DOS game. It's likely your Windows-7 installation is the 64-bit edition on a 64-bit machine, while the windows-XP installation was 32-bit software (which may or may not have been on a 64-bit cpu).

The transition to 64-bit has broken certain aspects of compatibility with old 16-bit applications. Most games from the 16-bit era are troublesome to natively run on windows.

Luckily for you, almost all such games were not actually written for windows^note: Instead, devs cut out the middleman and wrote directly for the underlying operating system: DOS. And we have some very good emulators available for this. Have you tried running the game using DOSBox?

note: At the time, windows had poor game support, and the hardware was too slow to share resources between the desktop and the game.
