BIAB 2019 update 622 (ultra pak on usb drive)full internal hd install win10 64

If I try to use the video, I get a message saying that VJT app is not installed. I installed 2019 update 622 as per the message box but same symptom.
This file is not on my hard drive, there is no VJT folder under \bb\data and I also checked the \bb folder on the ultra usb hd and that folder isn't present there either.

I have messaged support but has anyone got any clues as to how to fix this, please?
