How to play a Quicktime movie in Powerpoint 2010

Powerpoint 2010 is supposed to be able to play Quicktime movies as long as Quicktime Player is installed on the computer. I have the player installed but the MOV video won't play. My Powerpoint is 32-bit, running on 64-bit Windows 7. According to what I've read the Quicktime needs to be 32-bit as well for this to work, but I don't know if the player I have installed is 32-bit or 64-bit. Any suggestions?
