Hello, I successfully installed lightroom classic 12 on my computer (win 10 home), but when I try to run it, nothing happens. Lightroom asks me to upgrade the catalog once, when I upgrade it, nothing happens. I tried  reinstalling it, but nothing happened. On my second computer lightroom classic works.

The first thing that you should try is to switch off the GPU support from the Lightroom preferences and check if that helps to fix the issue.

Go to Lightroom > Preferences > Performance tab > Uncheck "Use Graphics Processor" > Restart Lightroom.

If Lightroom doesn't start correctly the please see "Solution 2" in the document behind the link below.

Another step is to try to reset the Lightroom preferences.

It's recommended to backup your preferences before you reset the preferences to the default settings:

Welcome to the Lightroom Community @Bety28758681cy0o. I'll try to help you figure this out.

Do you see Lightroom Classic in the Task Manager? Where is the catalog stored at the moment? In the internal drive or the external drive?

 

Try these steps:

  • Go to Task manager > Processes > look for Lightroom Classic.exe > End task/force quit.
  • Go to the Lightroom Classic's installation folder. (C:\Program Files\Adobe\Adobe Lightroom Classic - by default)
  • Right-click on Lightroom.exe & select 'Run as administrator'

You can also try pressing the ALT key at launch & select 'Create new catalog' & let me know how it goes. Thanks!
