Is there anyway to play a 32bit game on my 64bit system?

I have an Acer laptop, brand new with Windows 7 on it. I tried to download the game Grand Fantasia, but it does not work on my computer. It says i have to download a 32bit version of the game. My boyfriend has a laptop with windows 7 and the game works great on his, my sisters have a PC that is 64but like my laptop and it woks on theirs too. The problem is that I can not run the installer for the game, it just says download a 32bit or 64bit. Since my system is 64 I presume I need a 32bit. But the problem might also be the graphics card. I can not figure out how to find what graphics card I have in this computer.
