iQuipment PC icon (NotifyIcon) missing from the System Tray

After launch, iQuipment resides in the System Tray (usually at the bottom right corner next to the clock). Click the system tray button (1) to see a list of icons. Right-click the iQuipment icon (2) to see a menu. The iQuipment icon, in some Windows PCs, may not show up. When this happens, click the "Customize..." link (3). A window will pop up as shown below.

Scroll to find the iQuipment_PC entry from the list, then select the item "Show icon and notifications" from the pull-down (1). If needed, also check the box for "Always show all icons and notifications on the taskbar" (2).
