Important: If you are installing a driver upgrade over the existing driver, you can skip this section.

You must remove the existing software driver and driver components before you upgrade. To remove an existing driver and driver components, complete the following steps:


  1. Go to Control Panel and browse to Programs > Programs and Features .
  2. After the list of programs appears, select each of the following programs and remove them individually:
    • Easylon EIA-852 Interface
    • Easylon RNI Client
    • Easylon WLDV32.DLL
    Note: If you need to remove more than one program, wait until one program is removed before you remove another one.
  3. Restart your computer after all programs are uninstalled.
  4. In the Control Panel, browse to System and Security > Administrative Tools and double-click Computer Management.
  5. In the left pane, click Device Manager in the tree.
  6. In the right pane, expand LON Adapters in the tree.
  7. For each item listed under LON Adapters, right-click the item and click Uninstall.
    Note: The Confirm Device Uninstall window may appear when you select an item to uninstall. Use this screen to uninstall all items listed under LON Adapters. Select the Delete the driver software for this device check box and click OK. If the screen does not appear, continue to uninstall each item listed one at a time.
  8. Restart your computer after you uninstall all items.
  9. Type wldv32.dll in the Search box of the Start screen.
