I got it to work.
Maybe it's stupid luck but this is what I did.
The icon in the dock is a shortcut to Applications > Utilities > Adobe Creative Cloud > ACC > Creative Cloud.
I looked at the same item on the mac of a colleague.
I noticed that it said this was a program and on my mac it said it was an app.
I changed the name to "_Creative Cloud" and also copied the program of my colleague.
After I restarted my mac I tried to start the program.
Of course it didn't work.
I deleted the program I copied from the colleague and changed my own program back to "Creative Cloud".
After I restarted my mac again I started the program with the icon on the dock.
It took a while but Creative cloud started up and said there was an update.
I ran the update and behold it worked.
This also updated the "hdpin.db" that's in library > Application Support > Adobe > caps
I looked at this because someone on this forum suggested that changing the name of "hdpin.db" would work.
Which didn't.
Maybe you can try the changing of the name method and hope it works.
Thank you so much for your helpful reply. After reading your last response, the solution to my problem clicked in my head. I followed your suggestion and did the following to correct the problem:
1. In Finder I clicked on Applications>Utilities
2. In the Utilities folder I had two files that were labeled "Adobe Creative Cloud" and "Adobe Creative Cloud 3.7.0272".
3. I opened the file labeled Adobe Creative Cloud>ACC and renamed the file "Creative Cloud.app" "Old_Creative Cloud.app"
4. I shutdown the computer and re-booted the computer.
5. The Creative Cloud.app did not load when I rebooted so I had no active incidents of the Creative Cloud app in memory
6. Then, I used the Creative Cloud Installer that I downloaded from the Adobe website.
7. After I ran the Installer the Creative Cloud desktop app was installed with the latest version. 


Thank you so much for your suggestions and help. I had been working on this problem for two days and many hours of frustration. I hope anyone who has a similar problem will read this post .
