If you are all of the sudden getting an mmdriver.inf file missing error like the one below then I have an easy fix for you. Below I put a link to a zip file that contains the mmdriver.inf file, all you need to do is extract the zip file contents and copy the mmdriver.inf file into your  c:\windows\system32\ directory. This is for Windows XP, once you copy the file there will be no more errors.

  1. Thanks–worked great. After downloading, you must UNZIP the file, then copy the mmdriver file to C:\windows\system32\ directory. We restarted the computer for good measure.

  3. Thanks a million. I “upgraded” to a new version of Skype and it just took it upon itself to erase my file.
    After I did my reboot, there was no more “mmdriver.imf” file.

    I tried copying the file out of my Wife’s computer but couldn’t get it to work for some reason. Your link worked great.

    Thanks again for saving me hours of work.
