Photoshop CC 2019 won't open

[Joanna3]

A little more complicated actually. Old iMac -late 2009, but plenty of free space--running High Sierra and Photoshop CC 2015.5. I've had no problems for a couple of months since I installed High Sierra, but Photoshop refused to open today. I thought I might as well update it so I installed CC 2019. It won't open either. Neither version will. I tried to restart my computer but it says that Photoshop CC 2019 is preventing shut down, even after I force-quit it.

Perhaps I made a mistake in allowing it to keep preferences from the older version.

But what can I do now to get out of this situation?

Thank you!

I forgot to mention, Bridge 2019 does open.

Hi

Try using the Adobe Cleaner Tool

Use the Creative Cloud Cleaner Tool to solve installation problems

Thank you, that did the trick! It took a while but I'm good now.

What did the trick? I did the cleaner and removed it but than it still showed the icon and reopened uninstalled. Tripping up the whole thing. I restarted my computer, going to reinstall the app... Doubt it'll work though.
