Not with those specific apps, but I had issues with others, as posted here:
I tried for a few days to solve the problem, in-between project work, and when it looked like the only answer was to wipe the drive with a clean install of Win7, I purchased a new drive instead, and created another boot environment with Win8.
The only apps to malfunction on Win7 were Adobe apps, and they all began throwing errors at the exact same time. I'm sure there is a solution, but I haven't had time, or the need really, to keep searching for it.
It shouldn't create any trouble on Windows 7, 64bit.
Not done it yet - thinking about it so to be forewarned is to be forearmed.
Actually, there is a whole lot more information on Adobe forums now regarding my particular issue. It appears to be related to a program called "iLivid Download Manager":
The error message I was getting is all over the community forums, and it's not an Adobe related issue per se, as iLivid overwrites/corrupts important Microsoft DLL files used by certain 64bit apps.
I haven't had any malfunctions with Cloud apps otherwise.
