Describe the Bug

In Windows currently it's not possible to upgrade Sunshine from within a Sunshine session.

Error opening file for writing:
C:\Program Files\Sunshine\sunshine.exe

Which is understandable since it's running. However, Windows has a mechanism to replace files during reboot. The Sunshine installer should use this so that the installation can complete while running in a Sunshine session. Otherwise Sunshine must be turned off and then there may be no easy way to access the machine to perform the upgrade. This happens for example when Sunshine is running in a virtual machine.

Expected Behavior

Installer should complete and request a reboot.

If you choose uninstall previous version it will shutdown. beware, someone mentioned his config was gone by doing this.
i cannot confirm this, i always hit uninstall and the config got never deleted.
