Thanks, that was a vital piece of information.  On windows, pBuffers[1] indeed
contains the same data as pBuffers[0] does in wine.  Apparently the launcher is
hardcoded to look for the decrypted data in pBuffers[1].

I don't know how to fix Wine properly, but I made a totally ugly hack to copy
the first buffer into the second, and this was enough to make the launcher
happy:

+    if(idx==0)
+        message->pBuffers[1] = message->pBuffers[0];

     return SEC_E_OK;
 }

--- END PATCH ---

Now to figure out why Settlers 7 shows only a white screen in place of the menu
and crashes shortly after.
