How do I play a 32 bit game on my 64 bit computer?


I had a 32-bit Windows 7 Home Premium OS. I’ve got a 64-bit Windows Home
Premium. Now I want to play a certain game that only works on 32 bit. How do I
install my 32-bit OS and still have my 64-bit OS? I have two internal 500 GB
drives and two external 500 GB drives.

In this excerpt from

, I look at various ways to run a 32-bit game on a 64-bit

Running 32 bit on a 64 bit system

There are a number of different approaches to this problem and it really,
really depends on the characteristics of the game.

It is possible; I don’t know if you tried, but it is possible that the game
will just work. I know that I run 64-bit Windows on both of my primary machines
and they play games just fine.

I play World of Warcraft; I’ve mentioned that before and the game runs just
fine on 32 bit or 64. I really don’t see an issue there.

Not all games run on 64 bit

Now, not all games are like that; I understand that. Games often take a more
advantage of hardware specifics than your average run-of-the-mill application

Some of them do that in ways that aren’t necessarily portable between 32 and
64 bit.

Virtual machine

The first thing I would suggest is to see if the game will run properly in a
virtual machine.

There are several alternatives; I believe Virtual Box is the one that’s free
from Oracle (of all places). You could set up a 32-bit version of Windows in a
window in 64-bit version of Windows. Then you could try running your game in

The concern I have with that scenario (and the reason it may or may not
work) is that the game may rely too much on hardware specifics or direct access
to the hardware to work at all. If it does work, it may work so slowly as to
not be playable.

I think it’s worth trying because I find this the most flexible

You can leave your Windows 64-bit running and just fire up that 32-bit
virtual machine when it comes time to play the game.

Dual-boot system

The other alternative (and it’s not something that I touch on very often…
I try and avoid it if at all possible) is to set up a dual boot

You could:

  • On one hard disk, have 64-bit Windows installed
  • On the other hard disk, have 32-bit Windows installed

That way, when you want to play your games, you need to reboot and select the
32-bit version of Windows to start.

Personally, I find that very cumbersome. I don’t talk about it much at all
on Ask Leo!

Dual-boot scenarios… In the long run, most people find that solution to be
so cumbersome as to be unacceptable.

I strongly recommend you start with a virtual machine solution.

Use an old machine

The other solution that comes to mind is if you’ve got an old machine (a
second-hand machine) that meets the specs for the game, it might be worth it to
set up a second machine to play this thing.

It really depends on what your personal scenario is, what your personal
resources are.

Contact the developer

Finally, the last solution (of course) is to get a hold of the game

64-bit is definitely growing in popularity, by leaps and bounds, and the
game manufacturer needs to be addressing that. They should be pressured to

If they’re still in business, if this game is current, if they’re still
around, then they should be getting a lot of pressure to get their game to work
on 64-bit Windows. Because ultimately, that’s where everybody’s landing.

  1. If the game can’t be played on a 64 bit system because it’s REALLY old, you may be able to use DOSBox to play it. I’ve played things like Lode Runner, Dinopark Tycoon, and Oregon Trail Deluxe using DOSBox, and it’s pretty great for nostalgic encounters.

  2. the game was Far Cry played it on my XP os. like you said its not fesiable to go to a dual boot over one game or a vitural pc setup. i’ll stick with my W7 64 bit love it

  3. I have lots of PC casual games that are several years old and they all play fine on my 64 bit Windows 7 Home Premium. Windows sometimes suggests reinstalling with recommended settings, and I do this. As I understand it, 32 bit applications are stored somewhere slightly different than 64 bit apps (of which there are not as many as there should be at the moment). Almost everyone uses 32 bit web browsers with no problems (64 bit isn’t sufficiently supported yet) and unless you have OLD games (someone has already suggested DOSBox) you should have no problems with them. If you have got them from a game club such as Big Fish then customer support can be very helpful if you have installation or gameplay issues ;o)

  4. I am running windows 7 home premium 64bit. Let me explain how exactly I do. Starcraft 2 wont start again after I have started once. Starcraft 2 running in background. I had to close and reboot computer so I can start Starcraft 2. Why? Normal I use wow 64, but I did test wow too. Never happened before…I would like to know how to fix this.

    Would reinstall win 7 solve problem?

    No, I don’t think a reinstall would help. It simply sounds like starcraft isn’t exiting like it should. I’d try using Task Manager or Process Explorer to locate and kill the running Starcraft that remains after you’ve tried to exit it, and then see if it’ll start up after that.
