Unlock Space Engineers DLC

# Unlock Space Engineers DLC
# Sometimes required on multiplayer dedicated servers for players who have paid for the content but are unable to use it
# Created by Archi @ FrontRunnerTek.com (this is not an email address)

# Usage: Simply run the script. Edit the $SEinstallDirectory path variable below if you know it and want to speed up the process a bit.

# Manually Specify the install directory, or the script will try to find it, if that fails, it will display a folder selection dialog
$SEinstallDirectory = 'C:\Program Files (x86)\Steam\steamapps\common\SpaceEngineers'

# ========= CHANGE NOTHING BELOW!! =================================================================
