How to recreate Flash Professional CC preferences

Question

I recently downloaded Flash Professional CC to a Windows 7 computer. It functions extremely poorly: most dialog boxes don't work and many of them cause the program to freeze, so it can only be closed with Task Manager.
I called Adobe Tech Support. They emailed me a this link:
Re-create preferences
However, that link only refers to Flash CS6 and older versions.
I have some related questions:
1 - Is there a version of that link that includes Flash CC?   If there is I can't find it by searching.
2 - I went ahead and tried one method the link gave for deleting preferences. It said to hold down CTL + ALT + SHIFT while launching Flash CC. Here's a quote from the link:
Re-create the preferences file
Note: You can skip the following steps if you do not want to save your old preferences. You can start the application while holding Ctrl+Alt+Shift to delete and reset the preferences to the default.
I tried to follow this advice this in 2 ways:
     A - I held down  CTL + ALT + SHIFT while clicking on the Flash CC icon in my status bar. The icon froze and nothing launched. I rebooted.
     B -  I held down  CTL + ALT + SHIFT while double-clicking on the Flash CC shortcut on my desktop. It caused this window to open; it looks like a generic Windows 7 properties window, and I don't see anyway to "delete and reset the preferences to the default" as Adobe instructs.
Does anyone know how to delete Flash CC preferences?

Actually this needs to be updated for CC 2014. The file you reference above isn't in this folder. Instead, I see a 2014 folder and, inside this folder there is a file called cloudsync. See below. This is what needs to be deleted to prevent the crashing.
