Old Systems

I am trying to make this game for some kids I work but whenever I test it on their computer a warning box shows up saying the game is not a valid Win32 application. The computer I am making the game on is running Windows 7 64 bit with an Intel core i5 2.3 Ghz processor and the computer I want the game to play on is Windows XP with Intel pentium 4 2.7 Ghz processor. Also I export the game using the save game as runtime addon and copy all the dll’s and bundled python.

Thanks for any help/suggestions

i think the Intel Pentium 4 is has a 32 bit architechture while the game made is a 64 bit archtechture. So that explains why the runtime doesn’t work.
From what’ive heard of 32 bit applications should work fine on a 64 bit system, while the vice versa is not possible.

Will downloading the 32-bit version of blender and exporting the runtime from there work?

I think that would work.
