I received error message ERR:1333 in Hauptwerk 4 in an attempt to install my virtual pipe organ I just purchased. What should I do?

Certain Inspired Acoustics pipe organs require a license activation within Hauptwerk v4. The error message 1333 indicates that the license activation is yet to be done, and that prevents installation.

To solve this issue, please start Hauptwerk, generate a license update request file and send it to Milan Digital Audio through their website: https://www.hauptwerk.com/forms/license-updates/.

They will respond and send instructions on how to apply the license update, and after this process you will be able to install the organ without any error message.
