Adobe Creative Cloud Desktop App does not update (Error code: 86)

I'm trying to update Adobe CC Desktop App to v. 3.8.0.310 from the App itself, but NO GO!

That's the third time I try, and the third time it quits in the middle and nothing gets installed.

The App disappears from the Menu bar, when I restart, I'm where I was before: CC App calls for an update...

I when online to Adobe.com and downloaded the stand alone Adobe CC installer:
https://www.adobe.com/creativecloud/desktop-app.html

Ran the installer, which initiates a download of CC Desktop as well, in the middle of the download I get an error message:

"We've encountered the following issues:
Another version of Creative Cloud desktop is currently running. To Continue, please quit that instance and click retry. (Error code: 86)"

What the hell? Clicking "Retry" brings the same error message over and over.

This is what worked for me:
Download and run the Adobe uninstaller:

After this goes through, run the Adobe installer:

There! This time it worked. Ahh!  The bliss.
