The different version of MultiMSN patcher is available for each different specific version of MSN Messenger or Windows Live Messenger. The application of Multi MSN is pretty simple, just download MultiMSN that corresponding to your version of MSN Messenger or Windows Live Messenger, unzip the executable binary, and run the MultiMSN program. MultiMSN window will appear and allow users to select and choose which patch type that they want Multi MSN to fix into MSN Messenger or Windows Live Messenger. The options available are MultiMSN or SingleMSN, Hide Banner or Show Banner of Contact List Banner and Chat Window Banner.
As mentioned, since MultiMSN can only apply to the very specific version of instant messaging client that it supported, MultiMSN will check for version compatibility. If the messenger client is wrong version, “Version incompatible” will be shown on the window title bar. Some annoying though, the latest version of MultiMSN version 8.0.0812 has a pop-up message asking for donation.

Update The third party program to enable multiple MSN Messnger login is kind of obsolete. Instead, use the MultipleInstances hack to turn of multiple instances WL Messenger support to login to many accounts.
