I see the scenario here. You are mostly trying to register the systemVM template for HyperV as the first template (CloudPlatform setup is not complete yet, the zone for HyperV is the only one in this case); kindly confirm if this is the situation.
An workaround will be to enable NFS share on Windows - Server for NFS (natively available on Windows 2008 / 2012). Once the registration etc. is done, you may disable the NFS share.
