When a license .zip file downloaded does not show its content after getting unzipped, it can be fixed following the instructions below.

Solution #1:
Instead of pressing on the zip file itself (which is using the default unzipping software), right-clicked and unzip with another software: Right-click -> “open with” -> Select another app instead of the default archive utility.
If you do not have another app, you can install it from the app store: “The unarchiver” or another archiver.

Solution #2:
1) Open the finder and press CMD + Shift + G
2) paste this folder: ~/Library/Preferences/
3) delete this file: com.apple.archiveutility.plist

Based on other cases with Windows users we would suggest you extract the archive with the built-in Windows 10 archiver.
