it will not start anymore.

What happens when you try?

Please give a detailed description.

[WvdBerg Photography]

When I try to open it on my pc it is only running on th background and is not opening like it did before

[Per Berntsen]

Do you mean that nothing happens when you try to open it, but you can see the Lightroom process in the task manager?

[WvdBerg Photography]

That is correct. Only in the task manager.

[Per Berntsen]

Don't know if this will help, but try running LrC as administrator.

Right click the LrC shortcut on the desktop, then choose Run as administrator.

Make sure that it is not running in the background before trying this.

Sadly this didn't work as well. It's only running in the background.

Hi Per, any chance you know how I can fix this?

[Per Berntsen]

Here are a few more things you can try.

Before you try each one, make sure that LrC is not running in the background, and that there is no .lock file present. The .lock file can be found in the folder that contains your catalog. I think the default location is in the Pictures folder in your user account. If your catalog is named Lightroom Catalog v10.lrcat, the lock file will be named Lightroom Catalog v10.lrcat.lock. If there is a lock file present, delete it.

Try to delete Lightoom's preferences.

With the File Explorer, go to C:\Users\Your user name\AppData\Roaming\Adobe\Lightroom\Preferences

Delete the file named Lightroom Classic CC 7 Preferences.agprefs

A new preferences file will be created when Lightroom is launched.

If that doesn't help, try to disable the GPU in preferences.

Open Lightroom Classic CC 7 Preferences.agprefs in a plain text editor, like Notepad.

Close to the end of the file there is a line that says useAutoBahn = true,

Change this to useAutoBahn = false,

Save and close the file.

If neither of these help, uninstall LrC, then run the Creative Cloud Cleaner Tool, followed by a reinstall.

M1iMacにインストールしてみましたが、Illustrator、Photoshop、Lightroomは起動しましたがLightroom classicだけがユーザー権限でエラーが出て修復もできずに起動しません。
