Hello,
I am writing an installer for a program that uses an in-process COM server.
When installing this to a clean machine, it puts all the files in the right
place and registers the dll. However, when doing a major upgrade to a new
version, the files get installed correctly, but the dll file ends up not
being registered.
When looking at the log file from the installation, it first installs the
new version and registers it. Then it uninstalls the old version, and
unregisters it, and this seems to clobber the registry entries for the newly
installed file. Changing the install sequence to uninstall before installing
"fixes" the problem, but that's just treating the symptoms.
I suspect the basic problem is that in the two different versions there are
components with different GUIDs (containing the old and new version of the
dll file) which both write registry entries using the same COM type library
GUID. I'm quite clueless about both installers and COM, so I would very much
appreciate some guidance on the usual way of doing this like this...
To describe it in some more detail, my setup is as follows.
The COM server is hosted in a dll file called NCGServer6.6.1.dll, which I
want to put into the directory [Common Files]\NCG\NCGServer\6.6.1\ and
register. This dll file is put in a seperate merge module. I'm using WiX
2.0, so I include it with a snippet like
<Directory Id='TARGETDIR' Name='SourceDir'>
<Directory Id='CommonFilesFolder' Name='CFiles'>
<Directory Id='NCG' Name='NCG'>
<Directory Id='NCGServer' Name='NCGSrvr' LongName='NCGServer'>
<Directory Id='version6.6.1' Name='661' LongName='6.6.1'>
<Component Id="NCGServer6.6.1.dll"
Guid="{3A396C6B-B8A5-438e-B3D4-3FA365E27DD8}">
<File Id="NCGServer6.6.1.dll" Name="NCGS661.dll"
LongName="NCGServer6.6.1.dll" KeyPath="yes"
Source="D:\Dev\Installers\WiX\NCGServer MSM\NCGServer
MSM\Elements\NCG\Programs\NCGServer6.6.1.dll">
<TypeLib Id="{DA574677-4154-4FDB-876A-376EF6DCB3D2}"
Description="NCGServer 6.6 Type Library"
Language="0" MajorVersion="6" MinorVersion="6">
<Class Id="{2BCE5F13-4055-4001-9DD0-FB7D19815B6B}"
Context="InprocServer32"
Description="NCGServer Class"
ThreadingModel="both">
<ProgId Id="NCGServer.NCGServer.606.1"
Description="NCGServer Class">
<ProgId Id="NCGServer.NCGServer"
Description="NCGServer Class" />
</ProgId>
</Class>
<Interface Id="{B11969D1-0983-4D72-AA55-3E07D83A0CAE}"
Name="INCGServer" ProxyStubClassId="{00020424-0000-0000-C000-000000000046}"
ProxyStubClassId32="{00020424-0000-0000-C000-000000000046}" />
</TypeLib>
</File>
</Component>
The Component element is just derived from the output of heat.exe.
I then include the merge module in an MSI and install it and everything
works fine.
The problem comes when upgrading. I want to replace the dll file with a new
version and put the file in a new directory ([Common
Files]\NCG\NCGServer\6.6.2, say).
I'm doing a major upgrade, so I'm changing Module GUID, Package ID GUID, and
the GUID of the MSI I include it in. I change the directory name, replace
the file name with the new one, and change the Component GUID for the file.
I update the GUIDs in the typelib element for the new dll file by changing
the ClassId GUID but leaving the InterfaceID and TypeLibID the same (since
they are not affected by the upgrade).
When running this new MSI, this is what I see. First the registry gets
written with COM information:

Note how the key containing the type library ID is first written during the
install, then later removed during the uninstall phase.
