Hello Daryl007,

Thank you for contacting Infragistics.

In order to get the version of NetAdvantage you need I suggest registering your license key to your Infragistics member profile at following page: https://es.infragistics.com/my-account/register-product.
Once this is done, you can go to Account -> Keys & Downloads -> click over your product key ->  go to the tab "Service releases" and  and download the desired product package by selecting the respective license key.
Please let me know if you need any additional information on this matter.
