Hello John,
it seems, that I have also the problem of installing the fsuipc7. Your advices of executing "dir %LOCALAPPDATA%" and "dir %LOCALAPPDATA%\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache" show for the later command the found UserCfg.opt. But the installation of the fsuipc7 says that it cannot determine location of my UserCfg.opt file. As you told above, that it's better to solve the problem than to make manual installation, I try to do so by contacting you.
I am using MSFS2020 and wanted to use fsuipc7 to use mobiflight for some hardware-trials.
Kind regards, Gerald
