The built-in update system is available across all Editions of GLCV3.
It is a very simple system that will download an installer at the URL you specify then run it. It can be triggered by the versioning checks.
Update URL
You must specify the absolute, full URL to the downloadable executable file (installer) on your webserver (example: https://myserver.com/files/update.exe)
Force Update
This tells the launcher to not give the user any options, if an update is detected or triggered, this update must be downloaded and installed.
