Hi there,

Sorry that you're getting an error message while using Lightroom Desktop that says "Could not run script: LibraryFactory.lua".

You will see this message if you have a bad installation. 

• Try resetting the Lightroom app preferences to default? Press and hold the Shift + Option + Delete keys.(Mac) or Press and hold the Shift + Alt keys while
  starting Lightroom. A dialog box should appear asking you restore the preferences. Check if that helps. If not, check the next steps.
• Uninstall Lightroom CC via the Adobe Creative Cloud Application
• Restart your computer. 
• Use the Adobe Creative Cloud Application to reinstall Lightroom CC. 

Let us know if that helps.

Thanks,

Akash

Thanks for the feedback.

I tried the below but no luck.

I unistalled lightroom, but now I can't re install it as my laptop doesn't match the system requirements.?

Kind regards

My conclusions in this forum thread are this-

1) "Lightroom" was a perpetual Version (Version 6) for which Face Recognition ceased because of an 'expired' dll file.

2) The OP has a Mac with Catalina or BigSur 64bit OS that cannot install 'old' 32bit software.
