HP Sprinter License with QC ALM 11.0

Hi,

We have QC ALM 11.0 Enterprise Edition with Sprinter 11.0 as extension in our organisation.  Some of the projects want to make use of Sprinter so my question is do we need extra licenses (or specific licenses) to use Sprinter ? we already have 90 standard qc licenses.

Appreciate your response.

Thanks,
Venkat
