ok - here goes: affinity photo trial was still in my list of programs. I had originally upgraded from the trial program to the full version and after updating the trial never went away, so it was blocking other versions when i tried to update to the newest full version of AP. It would not uninstall either. Since i, using windows, i typed into google "fix problems that block programs from being installed or removed" and that led me me to a microsoft site which deals with this. i downloaded their update/download troubleshooter, ran the program and it was able to remove the trial version, after which i was able to install the newest affinity program and IT WORKED! ( i hope i dont have trouble with the next update!). Now to learn the program!
