There are several methods you can use to deploy the new Application (front End) version to all the users on the local network (LAN).

Here are some of the commonly used solutions:

1) Manually copy the file from the server to a local folder.

2) Use a .CMD/.BAT file to copy the new version from the server and launch the application (front End)

3) Use some type of auto-updater. This will automatically detect and copy a new version application (Front End).
