Product: Zoo
Summary: Outlines the system requirements for running the LAN Zoo.

• A Windows-based system that supports Microsoft .NET Framework 4.8
• A network connection configured for TCP/IP
• Virtual Machine host is supported
• Run All Windows Updates
• Computer with a monitor or display to run Zoo Admin Application

The LAN Zoo communicates using TCP Port 80. So, the Windows-based system you choose to install Zoo on should not already have other software running that uses TCP Port 80, including:

• Internet Information Services (IIS) for Windows® Services
• Apache HTTP Server
• Skype

If the Zoo service is not able to start, try these two updates:

• Latest Microsoft Visual C++ Redistributable Version
• .NET Framework 4.8 should be installed with your latest Windows Update. However, you can also download them from here

WPF is the GUI library that the Zoo Admin Application utilizes.

A WPF (Windows Presentation Foundation) application can run on a machine without a physical monitor, but it might not be visible or functional in the same way as when a monitor is connected. WPF applications primarily rely on a visual display, and without a monitor, it can't render their UI elements.

If WPF can’t initialize the display & all the display details so it fails. “Headless” computer setup with the Lan Zoo may display a blank dialog.

Workaround: Add a monitor. or Remote on the headless Zoo server with MS RDP (Remote Desktop Protocol) from another workstation. It appears that RDP provides what WPF needs & can display the dialog.
