After the Windows 10 creators update, CC desktop would not update PS or LR.  CC desktop fails with error code and message of "Another installer is running".  After several reboots, Adobe cleaner tool, registry cleanings, and searching through the Microsoft support sites the best resolution was to roll back the update to a prior version and reinstall the CC desktop, PS & LR.

I'm open to suggestions as to what may have caused the problem, but the closest I can come is that the interaction between the CC desktop and the Windows Installer Service was a bit wonky.

Wondering if anyone else was experiencing anything similar.

I installed 15063 last night, completed the reboots this morning and rolled it back to the previous version around noon.

I updated to Windows 10 Professional Creator Update 15063.138 without experiencing this error. Sorry to read of your difficulties. It must be frustrating.

I don't believe for one minute that this is an Adobe issue.  It's probably some other third party software that I have that didn't close correctly.  The only other thing I did before the update was to update the Topaz suite and restarted the PC after that.  I'll check the event logs to see if they show anything.

Final update:  Fixed!.  The problem I was seeing was resolved by technique from a long ago thread.  Hit the reset button.
  • Make backup copies of all presets for LR & PS (so I don't have to manually recreate them later just in case something goes wrong later)
  • Uninstall LR, PS and the entire CC desktop application (Yes Keep app preferences)
  • Restart PC
  • Ensure all the files are really gone.
  • Download and install new version of all the applications
  • make sure they run correctly (and my presets are there) which is why I made a backup just in case
  • Restart PC
  • Install Creators update.
  • Delete the backup copy of presets as they are all back.
The problem I was encountering was that there were so many older versions of LR and PS that CC was getting confused and the installer was appearing that it was still running.

Cleaning out all of the old code from older versions solved the problem.
