Ok. One of the things i did't figured out till now. What does this xCall thing

I guess this is the reason why the installer fails. Maybe i am wrong and this
is an error in the application program. but how to determin this?
Yes, this is likely the reason. Let me guess, you are trying with a
version of Wine that is more than a week old? Have you tried with the
current CVS?
is there a way to explorer all interfaces in an COM object (in the dll file)?
Not really. One way may be to disassemble the DllGetClassObject
function, but that would be more trouble than it's worth.

by the way: what is an apartment? (i think it has something to do with
thread/process, therefore i added the dll names for each Main call)
It is a unit in which COM objects are valid and is equal to or larger
than a thread, but smaller than or equal to a process. In practical
terms, it means that when you uninitialize an apartment all of the COM
objects that it exports are released and can no longer be accessed, and
similarly proxies to remote objects are invalidated and just return
RPC_E_DISCONNECTED.
Hope this helps,
Rob
