The version of this file is not compatible with the version of Windows you're running. Check your computer's system information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher.

How to fix this problem?

There is nothing you can do. It is Not compatible.

If this is a DOS game you can install DOSbox to run it. If it is a Windows 95/98 game you may be able to run it in Win XP. To install XP you need a license for it and install a virtual machine program.
