Can not open Wildcard certificate / folder looks empty

Question

A wildcard certificate is issued, but I receive an error when unpacking the certificate archive downloaded, what’s wrong?
Once i open the zipfile, the folder looks empty.

Answer

Sectigo (former Comodo) Wildcard certificates have a “*” in the file names, which is considered a prohibited characters in default Windows archiver, as a result - your activation tool returns an error or the folder will appear empty. Try using a free achiever tool like 7-Zip etc.: it mitigates this problem by renaming the files containing ‘*’ automatically.
