Our certificate import wizard doesn't properly support PFX files. It should be fixed to call PFXImportCertStore, and it also needs a dialog to enter the password if the file is protected.
If I work around that the import succeeds and the certificate is shown in the listview. It's not there when I open the control again, so it doesn't persist for some reason.
In fact it is stored in the registry, but we fail to parse it when populating the listview from the registry.
