Hi Bro
Frankly, I'm not sure about this tool.
Nonetheless, in my case, if I need to retrieve the licenses of my netorking devices e.g. ASA, ACS, IPS etc, I usually email licensing@cisco.com. Someone from Cisco will reply, within an hour from the time the email is received. Please be sure to use your company email, not from yahoo, hotmail etc. and state your CCO ID.
CCO ID = Username used to login to the Cisco website.
This is assuming, your company email and CCO ID is tied to the product's Serial Number.
Warm regards,
