P: Installer failing on macOS 10.15 Catalina

Amazing!! Worked for me, too, for Lightroom/Creative Cloud! Been trying everything for 2 days! Thank you, Matthieu!
You should put this solution into the other programs where "Adobe installer failing" comes up.

Splendid. It worked for me as-well.. Thank you.

THANKS A LOT DUDE! seriously, I've been cleaning all the little file of adobe for a while, until I found your tip! 

LEGEND

LEGEND!!!! Been looking for a solution for this for ages. Easier options - just delete all Adobe files in the utilities library. Solved the problem straight away.

Same here, 5.2%, trying the "safe mode" recommendation next

Here's what worked for me re: "Error code c151-Unable to create the symbolic link."

Apparently there's a hangup with ColorSync. I went to Library/ColorSync/Profiles and renamed the "Recommended" folder. I renamed it "Recommended_NOT" You can also delete it. When you go to reinstall PS CC it will create a new one, and should install without incident. Hope this works for you. 

As a data point, I installed Catalina last night on a newly formatted external SSD and then used the CC app to install individual programs. The biggest problem was finding the CC app download, otherwise it worked perfectly.

The only other Adobe-related issue was bad security settings on Microsoft VSCode, which is Adobe's anointed replacement for the ExtendScript Toolkit.

Thankyou!!

The same thing is happening to me. Please let me know if you got it to work
