When launching Help from within XrayVision (XV) that is installed on a network, the window will display a Table of Contents (TOC) but related content will not.

Microsoft Compiled HTML Help files (*.chm) will not open correctly if being accessed over a network. The help file will only display if on the local machine that is using the application.
Find the location of the install directory:
Right-click on the XV desktop shortcut then select to Properties.
Click on Find Target (WinXP) or Open File Location (Vista/Win7) and the install directory will open up in Windows Explorer.
Copy and paste the compiled help file XVAssistant.chm from the install directory to the user's desktop.
Double-click on the XVAssistant.chm icon that was just copied to the desktop and XV Help will display correctly.
