When I double click a Photoshop file to open it I get a Configuration Error (Error:1). I have uninstalled and reinstalled the Photoshop App and later uninstalled and reinstalled Adobe CC and still cannot open a file by double clicking. When I right click to "open with..." there is a delay and a greyed "Fetching" window that keeps me waiting for a while. I can still open Photoshop and then open the file from there, but this is something I'd like to figure out. I am running MacOS High Sierra 10.13.3. I do NOT have this problem with the other CC Apps. Any help here is appreciated!
I have the same problem on Windows 10 from the 26 february 2018.
No update or new installations on my PC
My version: Photoshop CS6 (64bit)
Take a look at this thread, although this is for Illustrator it may help with your issue
If that doesn't help try this
Creating a new administrator account did work, but... ugh. I'll look through the preferences and CC Cleaner Tool as well. Thanks so much for the tips!
