wine users - Nov 2009 - Re: Accessing a COM object's property throws "Object doesn'

Okay, that probably was a bit too much text for a first post...

Anyway, for the records, I was able to work around the issue by installing
dcom98 through winetricks (see http://wiki.jswindle.com/index.php/Dcom98).

I'm not a wine developer, but you should probably file some bug report, with
command line output and maybe some logs. This COM stuff is the most
sophisticated area in wine, and there are only a handful of guys  who really
understand COM internals, their time is limited, but they may be interested in
the differences (in the logs) between native and builtin DCOM (Windows DCOM
versus wine's DCOM).
