     if (rc != ERROR_SUCCESS)
     {
+        msi_free( package_code );
         WARN("Unable to query rev number: %d\n", rc);
         goto done;
     }

Save a line and move the msi_free a couple lines down to the done: block.

+    {
+        msi_free(source); /* This is correct because msi strdupW
calls msi_alloc. */
         return rc;
+    }

Are you serious?  Please take that comment out.  Either way the fix
isn't really right.  All you need is a 'goto done' because you're
still leaking the reg handles.
