John, as I said in my previous email, I copied it to the C:\Users\***\Documents\Prepar3D v5 Add-ons" folder per instructions. I did this prior to installation of FSUIPC6. Is that not correct?
Yes, I have a reasonably current version of my FSUIPC5.ini available.
I installed v6.0.3 to P3D V5 only. I copied a good copy of FSUIPC5.ini into "C:\Users\***\Documents\Prepar3D v5 Add-ons\FSUIPC6", renamed it FSUIPC6.ini. Took off with what seemed to be normal flight controls using X-45 joystick. P3D V5 recognized my joystick for a couple of minutes then did not respond to flight control inputs such as elevator, rudder, thrust or aelerons. Interestingly enough, after exit from P3D V5, I noticed that FSUIPC6 is installed in "C:\Users\***\Documents\Prepar3D v5 Add-ons" and in "C:\Users\***\Documents\Prepar3D v5 Add-ons\FSUIPC6". I would assume it belongs in C:\Users\***\Documents\Prepar3D v5 Add-ons\FSUIPC6". Am I correct?
Reverted back to FSUIPC5.15 for P3D V4.5. It now works fine again. Everything appears normal with P3D v4.5
FSUIPC6.0.3 installation for P3D V5 did not work. I ended up with 2 installations which I assume is the problem. Guidance please.
Thanks for the help.
