I did everything. Even run as administrator. The damn thing just doesn't work. I've spent 3 days trying to get this turd to work. I shouldn't have to do this. I love my Photoshop Elements 15 (which runs beautifully and installed without incident), but this Photoshop Elements 2018 is a giant box of crap. From my POV, I shouldn't have to have a degree in computer science to make it work. I have been with your support chat, and he couldn't make it work. This program is crap.
Initially, I was able to open Photoshop Elements 2018. After restarting my computer, I couldn't get it to load again. I did go into the "properties" settings and designated the setting to run as administrator. I did try using the menu, by right clicking and choosing, "run as administrator", but when I later went into "properties", I saw that the shortcut did not make the change.
I couldn't make it work, after designating "run as administrator", so I uninstalled the software and reinstalled it. Interestingly, this time it defaulted to the setting of "run as administrator", without me changing any settings. I got the program to open, closed it, restarted my computer and got it to open again. Hopefully it holds as a fix,
