For those wondering, I am running the 32-bit edition of Windows 7. I did this primarily for application compatibility above all else.

The first response from those who are familiar with 64-bit environments are quick to say, "But you can run 32-bit apps in a 64-bit environment easily."

That’s not always the case.

Running certain 32-bit apps in 64-bit environments can present itself to be a problem no matter what OS you use. For example, many Mac people use Photoshop. All new Macs are 64-bit. But Adobe does not have a 64-bit edition for the Mac. Photoshop still runs fine but doesn’t take full advantage of the 64-bit environment. It also ticked off Mac users something fierce that Photoshop 64-bit will be for Windows first. And if I were a Mac user that would perturb me quite a bit as well.

Per conversations I’ve had with a few folks running Windows Vista or 7 64-bit, two particular types of platforms have exhibited some quirks, also both from Adobe.

The first one is Adobe AIR. It would appear AIR doesn’t "play nice" in 64-bit world except for Linux currently. But on Windows 64-bit, AIR is something which may or may not work. So if you wanted to run AIR apps like Twhirl or TweetDeck on Vista 64 or Win 7 64, it might not even be possible presently.

Did you get Adobe AIR running on Windows Vista or 7 64-bit along with your favorite AIR apps? Let us know in the comments.

The second is a biggie, Adobe Flash. Some I’ve conversed with say Flash runs fine on 64-bit while others say it’s "tolerable" at best.

Did you get Adobe Flash running on your 64-bit Windows Vista or 7? Let us know in the comments on this one too as many would love to hear your experience.

Most people could live without AIR, but as for Flash, there are tons of web sites that simply require it. And going without Flash would be trying on the nerves to many.
