I stepped through the 16-bit installer machine code between the DdeConnect()
and the error dialog and this is the sequence of Wine calls:

DdeConnect
DdeCreateDataHandle -- fails at the check for pInstance == NULL
DdeClientTransaction -- fails at the check for pData == NULL in
WDML_ClientQueueExecute
DdeDisconnect

Then many hundreds (possibly thousands) of instructions later it calls
MessageBox to display the error dialog.
