• Install NewTek Network Video Send.exe.

• Install NewTek NDI AirSend Updater.exe.

  • You may need to fix the location of the dlls.

    Copy C:\Program Files\NewTek\NewTek NDI AirSend Updater\Processing.AirSend.x64.dll to C:\Windows\System32\

    Copy C:\Program Files\NewTek\NewTek NDI AirSend Updater\Processing.AirSend.x86.dll to C:\Windows\SysWOW64\

• Configure the CasparCG Server to use a Newtek iVGA output.

  (Even though it says iVGA, it will actually be outputting NDI thanks to the updated AirSend DLLs).
