Usage:
Run ""Launcher install"" as administrator to register protocol handlers.
Run ""Launcher uninstall"" as administrator to unregister protocol handlers.

Troubleshooting:
Run ""Launcher open extern://www.google.com"" as a user to test if the application can launch chrome.
Press Windows+R to open the System Run dialog and enter ""extern://www.google.com"" and click OK to verify that the protocols are registered correctly.
