Did you try redownloading the installer in case it got corrupted?
Are you quitting all running programs, virus protection etc?
The first thing to install with any update is the elicencer software, so maybe try updating this on it’s own first with the download from the elicencer site…you do have the elicencer connected I take it?
Right-click on the installer and unpack with any unrar/unzip software.
After that, you can navigate to the unpacked folder and run all installers separately.
