The installer of Paint.NET must be corrupted because its original size is around 62MB NOT 10MB as I see it in your screenshot, to fix this you need to remove it from this location so it can re-download: C:\Program Files\PMPC\PatchMyPCITProCache
Not sure about GitHub Desktop, maybe it's a corrupted installer too.
