How to change O365 Update Channel via deployment

Hello all

I am trying to run a Custom computer script to change the update channel on Office 365. There is a simple script to do this found here: https://support.microsoft.com/en-us/help/3185078/how-to-switch-from-semi-annual-channel-to-monthly-channel

The script immediately fails:

C:\Program Files (x86)\DesktopCentral_Agent\Computer\Startup\16204>REG QUERY HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun\Configuration\ /v CDNBaseUrl

ERROR: The system was unable to find the specified registry key or value.

SO I tried another method laid out here: https://blogs.technet.microsoft.com/odsupport/2017/05/10/how-to-switch-channels-for-office-2016-proplus/

I used a "Launch Applications" configuration, that did not work.

I used the above in a similar script from the first link, that also did not work

How can I deploy this change via desktop central and have it run either immediately, or scheduled after reboot. So far, I cannot get DC to properly run the simple steps needed to change the update channel on targeted machines.
