The latest April 9th update 2.6.6.18 throws an error when trying to use the -generateSslCert parameter on a first time HA deployment:

$parameters = @{
  ClusterStorage    = "C:\ClusterStorage\Volume1\Gateway"
  ClientAccessPoint = 'gateway-ha'
  StaticAddress     = '10.0.0.50'
  InstallerPath     = "C:\Installers\WindowsAdminCenter2511.exe"
  generateSslCert   = $true
}
