I had repeated problems installing Creative Cloud for the desktop, after it asked me to upgrade.
After renaming OOBE and using the cleaning tool several times, i got Creative Cloud to finally install.
But when I tried to run it, I get "Adobe CEP Service Manager has stopped working".
So I'm still dead in the water. This is just the latest of a string of problems I've had in installing
Creative Cloud for the desktop on my several PCs.
