Run an application only compatible with 32-bit on 64-bit machine

Title's pretty explanatory. I have an application(Second Life) that isn't compatible with 64-bit windows 7. It says that it is compatible with Windows XP, Vista, and 7 but only the 32-bit version of 7. I need to know if it's possible for me to download something to make the application compatible with my computer. I've run troubleshooters and ran it as windows compatible XP service pack 2 and tried again with service pack 3.

Um, i've run second life in 64-bit windows 7. Perhaps you need a newer copy of the game, or to update your video drivers?

I have run SecondLife on Win 7 x64 without issue in one of our teaching labs. The only thing I needed to do was to install the graphics card specific driver rather than the Windows 7 install default version.

Your question caught me by surprise as all I did was download and install it, didn't do any magic to get it working.

Although I have not personally installed this program, I do not see any reason a 32 bit Windows 7 program will not run on 64 bit Windows 7 (I'm sure there are certain exceptions to this). I have run numerous programs that do not state having 64 bit compatibility on Windows 7 64 bit. If there is an issue you can always run it in XP mode.
