[Wine] Is Wine supporting .tlb files

[Timeout]

In the course of the installation of trados, I have the runtime of the installshield ISProbe.tlb failing with error 2 (not found), although it's correctly there as well as dao2535.tlb of microsoft shared (not there but I could get it from the XP installation).

Questions are: Why is the first seen as not found although it's there - is this a registry problem?
Are these files important (DAO) and is it enough for me to copy them from the windows installation (which would maybe bring me back to first issue)
