EHX Hotfix

Microsoft® released an enhancement to the memory management features in .Net 4.6.2 and included it in automatic Windows Updates. 

Unfortunately this change caused some EHX versions to fail at start-up, with the message "Object reference not set to an instance of an object" shown in a dialog box immediately on launch.

There are three methods to resolve this issue:

  • Use the CC Hotfix tool.
  • Undo the Windows Update as documented in this Solution.
  • Replace the EclipseClientLibrary.dll file in your EHX installation directory with a patched version from this page.

Step 1: Locate your EclipseClientLibrary.dll file (usually found in C:\Program Files\ClearCom\EHX Configuration System).
Step 2: Upload the dll file below by clicking Choose File, selecting the dll then clicking Upload.
Step 3: Download the patched file and replace the original file. If a patch is not available, further instructions will be provided.
