After installation of a wildcard SSL certificate into the certificate store, the certificate does not appear in the IIS certificate list for use with site bindings.
I had a key file & a crt file but it wouldn't show in IIS because I couldn't attach the key to the certificate during the import. Ended up creating a pfx file containing the certificate & the key, and after that it worked (When importing to the computer and not local user)
Created the file with OpenSSL (Download first).
openssl pkcs12 -export -out domain.name.pfx -inkey domain.name.key -in domain.name.crt
