How to active offline a teststand 3.5 license

[RaulEH]

Hi,

Im dealing with an issue trying to set offline a teststand license from teststand 3.5. I have the serial and computer ID but the latest changes on the NI website to execute this is not showing the NI Teststand option and if I try to open a service request, once I set the serial the page is showing following messange "We're sorry, we don't have a match for the number you entered. Please try again or click Next to try a different way to submit an activation request." 

Any idea what can be done to get the activation code?

Thanks in advance
