Is this after an upgrade or a fresh installation?
What operating system?
What version of Photoshop?
Do other Adobe software start?
I have heard of a damaged Adobe Application Manger causing problems. You could uninstall it, then use Adobe Cleaner tool, then reinstall.
Yeah, programs like Premiere Pro and After Effects work, but I have yet to try anything else. And I'll give that a go, thanks for the links
It's just a fresh installation, I'm on Windows 7 Professional, and I'm using CC 2018 but as for what version exactly let me find out
