For everyone, the reason we didn't saw any siteproperties was because the API must be installed in all environments. After we did that we could see the siteproperties (and services and times).
We only got the problem that the application icons aren't shown yet.
Niek, security isn't included in this version I also noticed. Gonne open a separte post for that one, it is possible with the lifetime security api's .
Kind regards,
Evert
