View Full Version : Question: Why does COM extraction leave HKCR\Interfaces ?

04-18-2006, 08:01 AM
As I understand it ... when a COM server containing entries in the TypeLib Table is installed, the Type Library is registered by calling Oleaut32::RegisterTypeLib which writes out the HKCR\Interfaces keys.

When InstallShield's COM-extraction is run, these keys are left in the registry table.

If these keys are generated at runtime then are they necessary in the registry table?

They are required if you use a custom ProxyStub. If you use the standard ProxyStub ({00020424...}) These entries are not required.

I need to do some more investigation before adding this filtering to our product. I know at one point we did filter these, and then made a decision to not filter them.

I do not believe it does any harm to leave these entries in the registry table. However it does contribute to MSI bloat.

Thanks for the feedback.
