Windows 10 + Corrupted Live Video

This applies to Windows 10 and above and MXWendler version 5.0 and above with AJA Kona 5 (and maybe other) capture cards installed.

Problem

The capture card is not visible in Settings->Live Devices

Solution

You have to manually install the DirectShow drivers

1. Download the driver
2. Unpack driver in location where driver can stay. You must not delete or move the driver later.
3. Locate this location with the explorer
4. Copy the location path in the adress line
5. Register driver as admin via command terminal:
   1. Click on 'Start'
   2. Type cmd
   3. Right-click CMD-app 'Start as Administrator'
   4. Navigate to the drive and folder where the AJAMultiCapture64.dll driver with the command cd D:\to\my\folder and paste the path copied before (copy/paste will not work, because it is an Administrator Shell)
   5. type regsvr32 AJAMultiCapture64.dll

Register AJA Kona DirectShow driver

Tip: Sometimes Stage Designer / FXServer complains with 'Cannot find VIDEOINFOHEADER' and does not open the device. In this case, set the AJA capture format to RGBA8 and restart the computer system.

Background

The AJA Kona driver comes with a broken DirectShow installer and driver. You have to register the device manually as admin so it can be found by other software.
