Another thing to check is whether the name of the exported function from the DLL matches the one you call from the msi. It may be decorated (e.g. [EMAIL PROTECTED]) in the DLL whereas you've specified it as "function" in WiX. If this is the problem, either use the decorated name in WiX, or get the undecorated name in the DLL.
