// upgrade installer that is downloaded and run will fail. This is because it cannot overwrite
// C:\ProgramFiles\GVFS\GVFS.Upgrader.exe that is running. Moving GVFS.Upgrader.exe along with
// its dependencies to a temporary location inside ProgramData and running GVFS.Upgrader.exe
// from this temporary location helps avoid this problem.
