Hi,
Yes I have followed the instructions above.
I have paid version Revo Uninstaller Pro that completely uninstall everything.
My Purchase are from the developers directly or from ORBX or from Fight Sim.to or from SimMarket etc.
MY Flight Simulator was purchased from the Microsoft Store.
I have nothing to loose by starting from scratch other than the time it takes to fully remove everything and the time it takes to reinstall everything and update everything.
Thank you
