Message Name:SID_SWITCHPRODUCT
Direction:Client to Server
Used By:Warcraft III The Frozen Throne
Format:

(UINT32) Product ID

Remarks

This message is used to switch from W3XP to WAR3.

When running WAR3 with W3XP installed, the client sends both WAR3 and W3XP keys in SID_AUTH_CHECK and uses W3XP as the Product Id in SID_AUTH_INFO. After a successful SID_AUTH_CHECK, the client sends this message with the Product Id set to WAR3 to make the switch from expansion to non-expansion.
