Please note: This is a legacy article and is only available to users who purchased education access to GameMaker 8.1 prior to the end of its support.
This only applies to GameMaker 8.1 and it is not available for GameMaker: Studio or GameMaker Studio 2.
For classroom use, only the full version (not Lite) can be installed using an MSI.
The version we provide for personal use by the students at home or outside of class on their own machines does NOT work with an MSI and must be installed on each PC as it uses a secure DRM that needs to be authenticated to the hardware. http://help.yoyogames.com/entries/21951091
The free versions are not designed to be run on a school network, and though we allow schools to use the free versions of our software, they install on a per user / per machine basis and we do not offer any support for free users.
