I cannot get Lightroom to open.  It is only running as a backgroun program.  I have tried rebooting, uninstalling both the lightroom app, as well as the Creative Cloud app.  Thanks!

I've found this same problem with Chrome several times. You start it, it doesn't show up listed under Processes, for live apps, but only Details, which lists all the programs.

I suspect this is a Windows issue rather than a Adobe issue.

As a test, try right-clicking on LrC and run it as Administrator.

I saw that you were having trouble setting the priority in Task Manager as described in the older thread here. I thought I would give you a little more detail on how to do that, in case you want to try this solution.

 

1. When you first open Task Manager, you may see the summary view. If so, choose "More Details" at the bottom:

2. In the detailed view, you will see the disclosure triangle next to Lightroom to allow you to expand to show the sub-processes:

3.  Right click Lightroom Classic, and Choose "Go to Details."

4. In the Details view, right click Lightroom.exe, choose "Set Priority," and change to "High."

Did LrC close properly last time you used it. Or did it crash? Or dud you force quit?

Either of the latter would have not deleted the lock file.
