Photoshop was removed from my computer and I can't download it. I still have all creative cloud apps like LR but Photoshop is gone

To be clear, Photoshop isn’t gone. It’s still there and still working if you look in Program Files, and you can probably still start it up from the Windows Start menu.

What happens, and we’ve seen a few cases of this, is that the CC desktop app loses the link to Photoshop. In other words, this is a CC app problem, not a Photoshop problem.

You can repair the CC app as per ​@Peru Bob ‘s instructions. But before that, you can also try to sign out of the CC app and then sign back in. This will force a rescan of all installed apps.

Try resetting the CC App.

To reset the Creative Cloud desktop app, make sure it's in the foreground, then press:

Win: Ctrl + Alt + R

Mac: Cmd + Opt + R

If that doesn't work, try uninstalling and reinstalling the CC App:
