Hi,
Last week I posted a query about our COM+ application getting reference
counts on running a repair install. I realise COM+ is one of the darker
corners of installer technology but I'm still scratching my head on this
one.
The reference counts in HKLM\Software\Microsoft\Windows\SharedDLLs is
incremented by the COM+ catalogue services during a repair, probably as part
of the API calls made by the ComPlus custom action in WiX. The repair log
shows it going through an uninstall/install process which appears correct.
Now I'm wondering if my authoring is incorrect. I hadn't realised the COM+
catalogue service causes self registration and I already included a file and
typelib elements to ensure correct registration. Would this be a problem?
This is one of the COM+ components installed as a separate COM+ application.
After repair the SharedDLLs reference count is 3. The count doesn't exist on
straight install/de-install.
