Windows live quicktime control host stopped working solution
The error comes from MS Windows Live or Photo Gallery.
First thing to do is Re-download and re-install them from MS and see if that fixes the error. here is the link http://download.live.com/photogallery
If this does not work, remove windows live photo gallery from your PC and the problem should be fixed.
Another thing you might want to try is to uninstall quicktime and reinstall quick time, this might work for some people.
This bug seems to only occur on windows 7 64x opertating systems only and i assume this bug will be fixed on the next windows service pack.
