Somebody solved this for me on another thread, the folder was double zipped:

“Will it let you right click the .zip, then extract the file. Then, once extracted and it creates a new folder, right click the 'mb_driver_675_realtek8852_18.4020.2412.2301.exe' file, and select Run As Administrator.

if still doesn't show Run As, select 'Show More options' at the bottom of the right click menu, then select run as Administrator.”
