RealVNC install on RPi4 with UbuntuMate 20.04.1 LTS

This is a lot of help! I am having trouble at the very end. Once I get to the final step I encounter an error.

EDIT: I guess that this was the OP's error, but I have done all the steps in the solution and am still getting the error.

I login through the VNC server licensing window and apply changes to my computer to add it. and then when I hit apply, I get the following messages:

In the licensing window: "Failed to read configuration"

and in the terminal:

/usr/bin/vncserver-x11-core: error while loading shared libraries: /lib/libbcm_host.so: invalid ELF header

What steps are needed to fix this?

Thanks!
