  1. Locate the software driver folder found in Step 1 of Installing the new LonWorks software driver. Use the following file path if you are unsure of the software driver folder’s location:

    C:\Program Files (x86)\Johnson Controls\LCS8520\X.X.X.XXXX\Easylon-wdm_vx.x.xxxx-JCI (where X is the Metasys software release and build number, and x is the software driver version number).

  2. In the software driver file folder, open the EasyCheck folder, right-click Setup.exe, and select Run as Administrator.
  3. Follow the instructions on the screen to complete the installation. Accept the default installation location: C:\Easylon.
  4. When the EasyCheck application installation is complete, open the RniLonCl.Svc folder.
  5. Double-click FastUpd.exe if you are installing driver upgrades over existing drivers; or, if you followed all instructions and removed the necessary drivers before upgrading, double-click FastInst.exe.
    Important: Do not run FastInst.exe if the RNI client software and LON Adapters are not removed in advance. Problems can arise when multiple LON Adapters exist.
    The file installs the RNI client driver.
  6. Install the application in the default directory C:\Easylon.
  7. Type EasyCheck in the Search box of the Start screen.
  8. Select EasyCheck from the Apps results.
