I would assume that if the 3rd party COM library is not installed, then when 
you tried to CoCreateInstance or QueryInterface one of the COM objects or 
interfaces in the 3rd party library, then it would fail. E.g. 
CoCreateInstance failing with REGDB_E_CLASSNOTREG, or QueryInterface failing 
with E_NOINTERFACE.

You may wish to consult the documentation for the 3rd party library to see 
if they have any specific techniques that they recommend.
