Thank you for posting in the Intel Community.
If your Gaming Bundle Master Key shows invalid, your PROMO CODE is temporarily unavailable, or if your code does not work for software titles, follow these steps for a new Master Key or new code for software titles:
1. Is the Master Key entered correctly? Make sure there are no spaces before the first character of the Master Key.
2. Are you using the correct URL for your Intel® Game Bundle or Intel® Software Starter Pack? This URL can be found on your Master Key printed voucher or in the Master Key delivery email.
3. Are you using a supported website browser? Gaming Bundle Master Key or Specific Software Title Code supports Internet Explorer 10* and above, and the most recent versions of Google Chrome*, Safari*, and Firefox*.\
If the issue persists visit https://softwareoffer.intel.com/Redeem and click on "Support" located at the bottom of the page. You may need to provide the proof of purchase (invoice) of the qualifying product and the screenshot of the error when support contacts you back.
Please fill out the form and kindly wait for a response.
Hope this helps.
