startmovie h264 not working

startmovie h264 yields the following error:

And, of course, endmovie yields:

Even though I do have QuickTime installed. I also tried installing other software like DivX and CCCP. Google search doesn’t provide anything that solves the problem.

I know I can use tga/jpg + wav, but I’m tired of the extra time it takes to make the demo into a video.

I’m using Windows 7 64-bit.

Any suggestions?
