I applied http://winehq.org/pipermail/wine-patches/2006-July/028696.html
and then ran
  wine PSDK-x86.exe
This gets further than before (cf. bug 5392), but it
now seems to crash in ACTION_AppSearch:

This is probably an easy bug to fix for an MSI developer;
ACTION_AppSearchComponents always sets value to NULL, so the
crash happens if ACTION_AppSearchComponents succeeds.
I'll attach a +msi log for grins.
