OK, I created an installer, here is what I did, and it seems to work.
1. Extracted the files from the CAB file.
2. Created new project in AI.
3. Under files and folders, added windows\downloaded program files folder.
4. Copied the dll, inf, rll files into this folder, left the CAB file in the Application Files folder as a temp file.
5. Created a COM object, created from the DLL from the CAB file and gave it the CLSID from the inf file in the CAB file.
6. Set the DLL to auto-register.
7. Built the package.
