And what I said was factual. Buying it on steam, adds one more layer to the install process. You may have to just delete the whole package located at:
C:\your profile\appdata\local\packages\Microsoftflightsimulatorx xxxxxx Just delete this whole directory, then clear out deleted files, shut down pc. Restart PC, then at admin command prompt run the following command:
“dism.exe_/online_/cleanup-image_/restorehealth”
Personally I would at least run:
sfc /scannow - to make sure file structure is good. If you think your memory is in question you can in “search box” run: mdsched.exe - that will launch a windows memory check, takes a while.
Hope this helps. Keep us apprised on progress.
