The message you have mentioned is only a warning created prior to 1.30.2 being released, to help ensure users backed up their client. The game can be installed anywhere on the computer and it wont affect games not showing up in the LAN menu.
Guide on how to use the wc3connect client is at the following link:
http://wiki.entgaming.net/index.php?title=WC3ConnectBe sure of the following:
- Ensure the game version is 1.30.1 by looking at the version number on the lower right of the main menu
- No firewalls are blocking the wc3connect client
If your version is wrong, be sure you've downloaded from the wc3connect topic
