I currently have my Office apps installed from the LTSC channel package. If I want to change to the beta channel can I simply download that package and run the installer?
Security warning, Downloading the tool from your mediafire or upload.ee links resulted in a pop up that hijacked MS Edge [soon as you open the site page] and provided fake downloads that were not archives, I had to re-image the newly build laptop to get ride of the spam of fake scammer AV pop ups that were injected into Edge that were from "every" AV vendor. Firefox with Ublock Orign blocks the hijacking pop up and allows the download of your archive. I would recommend placing the clean files on mega.
