Press Check for updates to get it.
The Radeon Software Adrenalin 2020 Edition 20.5.1 installation package contains the following:
Have not updated Windows Pro 64bit to 2004, still on 1909. Anyways trying to update and Windows indicate that it cannot run this file. Is this normal since being on 1909 yet?
That is interesting, downloaded 3 times in Edge and last two times got could not install for this version of Windows, check file or something like that. Used Chrome and installed, working so far.
In Edge while downloading first time I clicked on view Downloads and it stopped downloading the file so I deleted it. Then started to download again and it appears it would just bring back the previous partial file and not download anything more. Anyways working now.
