I am using:
Windows 8.1 64bit
Photoshop CC 32/64bit 14.2 (Updated last night)
After updating failed a few times, on the 5th try it finished.
Everything in the 32bit version works fine, however in the 64 bit version I am missing file formats (unable to open/save tga's, pngs etc) the generate feature is missing, half of the filter features are missing) liquify, gallery etc.
So after 24 hours I gave up with online support. I uninstalled and reinstalled and now they both work. It was very practical and to be honest, it really annoyed me because it used half my data allowance for the month.
