Didn't starting if .exe.config didn't exist

[de-served]

If there are no HostsFileEditor.exe.config file then trying to start HostsFileEditor.exe will fail - program closes.
It must start with defaults and if necessary (something changed in settings/windows pos) - recreate config?

UPD: config parameters ignored.
Changing to

      <setting name="WindowLocation" serializeAs="String">
        <value>0, 0</value>
      </setting>
      <setting name="WindowSize" serializeAs="String">
        <value>1920, 1054</value>
      </setting>

does nothing.
