It's fixed!  Everything's working!  After much googling and reading I backed everything up just in case I decided to erase, format & re-install everything.  But I did not need to.  (In order to back-up everything, I needed to borrow an extra internal hard drive from a friend and install that in the computer. 1) Yesterday I booted to my Windows 7 Home O/S disc and ran Repair a couple of times -> did not fix.  (In order to do this I had to     borrow a DVD-drive from the same friend & install it in my computer as my two DVD-drives decided they were not working anymore.) 2) Came across an article about running sfc /scannow -> would not work 3) Googled to find out why that wouldn't work and came upon an article to that issue.  I forget the commands at DOS but it had     something to do with trustedinstaller.  Whatever it was it allowed me to run sfc /scannow aftewards though it said nothing was     wrong. 4)  Uninstalled both PSE 9 and PSE 2019 so I could re-install PSE 2019 (just in case there was a conflict with PSE 9) 5) restarted the computer and it was incredibly slow.  To the point where I wanted to give up and take a baseball bat to it.  I was     seriously thinking of erase, reformatting my drive and re-installing everything when I suddenly realized Windows Update was     running.  I haven't been able to get updates to install for a couple of years now!  5 hours or more later yesterday, Windows     Update was done!  Over 170 updates. 6)  Today I re-installed PSE 2019 and came up with a different error when trying to launch the program.  Error 16.   Googled that      and found an extensive article on fixing it involving permissions.  Turns out if I right-clicked the PSE 2019 shortcut and said to run      as administrator, it launched!  But not if I double-clicked or tried to run it from the Start Menu.  I got lost in all the information of      permissions, folders and users and phoned Adobe.  The gentleman I spoke with fixed the permission issue and I no longer need to      right-click and run ad administrator. Thankfully all the work I did using/saving in PSE 9 loads into PSE 2019 as well. ... View more
