If you want to use the auto host option in Lan Messenger you'll need Lan Messenger V1.5.0 or newer and Map Launcher V2.8.8 or newer. If you have this you can enable the auto host option in Lan Messenger by following the steps: 1) Open Map Launcher and auto host (click the "actions" menu and click "make map list (auto host)") NOTE: close Lan Messenger. 2) Click the "add-ins" menu at the auto host screen and click "LAN MESSENGER". Lan Messenger should start now and the auto host option should work.
NOTE: If the "LAN MESSENGER" isn't in the "add-ins" menu you need to add it yourself by clicking "add-in manager" and clicking "add" then you need to enter "LAN MESSENGER" as description and LAN_MESSENGER.ClsConnection as clsid. Now click the "save" button and Lan Messenger should be in the actions menu now.
