Installing COM Interface

Hi, first time using PDFCreator, honestly an awesome product. My problem is I need to use the COM interface in one of my c# web apps but I don't need to install the whole PDFCreator application(actually I would just need to convert word docs to pdf files programmatically).

What I envisage is to just install the COM interface manually for this so I could use the InterOp assembly for .NET, If someone can kindly help me with this one I would greatly appreciate it. And would this be suffice for what I'm trying to do?

Thanks in advance.
