I had to do a clean install today due to corrupted files and system compromised

No, I’ve had it with their planes a few times. If you try to delete its folder with the sim open it will fail as some of the files are open, even if you cancel the update process. My guess is the downloaded archive fails to extract correctly as it cannot overwrite these locked files. For me it was a handful of fonts files. Close sim, delete folder, then update. It doesn’t even need to download the archive again, it just extracts it.
