Can't open ProRes 422 in AE or Premier CS5.5

I have provided footage to colleagues in India. The footage is ProRes 422 (HQ) files. They work on PCs using windows 7. They say that they cannot get the clips to open in Aftereffects or Premiere 5.5. (Sorry I do not know the exact version of 5.5)

I too have a PC running windows 7. I can open and work with the files in AfterEffects CS 5 (V10.0.2.4). I also have Quicktime 7.7.1. It all just worked for me. I did not need to load any new codecs. I just opened the files directly and could edit them.

Any obvious steps they should try such as...
Update quicktime to latest version?
Update CS 5.5 (any recent patches specifically for this?)?
Do they need a codec not present in the Cs 5.5 installation?

I had another colleague mention that this was a known issue. That CS 5.5 AfterEffects and Premiere will not open proRes files. Is this true? If yes are there any work arounds?

Maybe they need to add the ProRes codec to their QT : [support.apple.com]

Also, isn't it a bad choice for working on a PC, since PC's can't (I think) encode ProRes, only read it?

That's only in QT. FFMPEG now encodes and decodes all flavours of Prores including LT and Proxy on PCs. And in 10 bits too. Here's a GUI:
