Thinkpad X60 – Reinstalling Sierra Wireless MC5720 Verizon Modem on Windows Vista

I recently had issues reinstalling drivers for my Verizon 1x-EVDO embedded modem in my Lenovo Thinkpad X60, Sierra Wirelsss MC5720 Modem, couldn’t find much help, eventually found one messageboard that helped me out.  Thus, I post my discoveries in hopes to help the next one out there.  Pass it on, right?

So my issue – I reinstalled Windows Vista and was able to get every driver for my system installed without issues from the Lenovo driver website.  However, for the life of me, I couldn’t get Windows to accept the driver location of Lenovo’s recommended driver download for the Sierra modem, thus rendering Access Connections and Verizon’s EZAccess programs useless.  Well here’s how.

  1. Download Sierra Driver: This is the driver file I used, downloaded and used as of this posting.  There may be a more recent version on Lenovo’s website – Sierra Wireless MC5720 Driver – MC5720AC.MSI
  2. Don’t install the MSI file!! Just download it and save it to your desktop.
  3. Use a program such as Universal Extractor to extract all of the contained files from within the MSI file.  .MSI files are essentially a type of .ZIP or .TAR file in that they are a container for multiple files.
  4. Once all of the files are extracted, go to your Device Manager and right-click on the Sierra Wireless MC5720 that is listed under the Unknown Devices and choose Update Driver.
  5. At the prompt, tell Windows to look in the folder of the extracted files from the .MSI file
  6. Success! Once the primary driver is installed, there will be four or five other network device and comm port drivers that can be installed the exact same way.

Feel free to comment on if this works for you or not.  I hope it helps!
