    Is the Pantech card listed in the add/remove programs?  If so remove it.  Also remove VZ access manager.  After this is done go into C:\Program Files and remove any VZ or Pantech folders.  Reboot and run the install again.

    Accepted Solution

    What you can try is:

    Unplug the modem from the PC.
    Remove everything, VZ access manager, and the pantech entries in the add/remove programs. Then open up the device manager and remove any of the pantech modem entries in there, if any. Then reboot your computer.

    Now run the VZ access manager install setup but dont plug the modem in yet. During the setup it should ask you to insert the modem. Then plug it in.  It should install it fine then.

    Hope this helps
