Section 6b applies only when the LGPL object is "already present on the user's computer system", that is, when installed by the user from other sources and your code just dynamically links to it. Whomever they got the binary from must comply with one of the other methods in section 6. If your installer supplies the LGPL DLLs, 6b doesn't apply to you. You will need to be prepared to offer the source code if you don't ship it with your installer. If you are getting the DLLs you use from a compliant third party, and they cease operating, you are still required to offer the source code for the versions you shipped. Maybe as long as three years later. Of course, I Am Not A Lawyer, and you are free to disagree. You should consult a real lawyer for a more definitive opinion.
