Hi and thanks for the response. I decided not to use the uninstaller at this time, as the instructions clearly state that *all* Adobe files will be removed. I cannot afford the downtime right now (client projects), so losing many hours to making absolutely sure everything is backed up (from the myriad places preferences, settings, plug-ins, etc., get "tucked away") and then uninstalling and reinstalling all of the various Adobe applications and settings is not an option.
The machine where the problem exists is a Windows 7 pro (64-bit) machine (Intel i7 CPU, 48GB RAM). We have this particular machine set up with the CS6 Master Suite, because CS6 is the last time things were *stable* (we weren't constantly worried something would break with an update or new "feature"), but someone decided to install Creative Cloud suite on that machine, and it's basically acted like a virus taking over "all things Adobe" on the machine.
I finally got the desktop Creative Cloud application to stop hanging when attempting to connect to Adobe (various tries re-installing with the Adobe CC Desktop install executable and "repair" using Windows' uninstall interface) and then used another CC login to at least be able to access the CS6 Master Suite applications that we paid for. The only way to access CS6 is by logging into a Creative Cloud account. Trying to open (directly) any CS6 program results in being immediately taken to the Creative Cloud desktop online login. Even though CS6 is paid for, it can't be accessed without a paid Creative Cloud subscription. I assume you can understand why this is infuriating (and even seems like it might be illegal: preventing someone from using a product they have already purchased until they purchase another product they don't want).
I tried the "solution" shown in this thread (Re: Stuck on "Please Wait a Moment" when trying to launch InDesign... help! ), but it only resulted in an Adobe notification popup window telling me I needed to do a complete uninstall/reinstall of the Adobe CS6 Suite. Luckily restoring the deleted files and folders resulted in CS6 working again (albeit with the caveat of having to login first with a CC account).
At this point, I just wish CC hadn't been installed on this older machine, because it was nice having a "safety" machine that was always reliable from back in the days when I didn't have to worry about constant problems and changes from a subscription based design suite.
