When I open Photoshop Elements with one of my catalogs I get the following message. If I try to run Optimize or Repair the my computer freezes!
Try updating Windows.
Then update the graphics driver. If NVIDIA graphics, make sure to use the latest Studio Driver from NVIDIA (NOT the Game Driver).
My Windoze is up to date.
I just updated my GeForce GTX 1070 to the latest Studio Drivers and no change. I get the same pop up message.
This list of stuff is crazy long! Most of this stuff I have covered.
There are a bunch of obscure items on this list that I shouldn't have to do if Adobe would have done their job with this program!
