When you run the Media Creation Tool (MCT), you may see the error 0x80072f76 - 0x20017
:
We’re not sure what happened, but we’re unable to run this tool on your PC. If you continue experiencing problems, reference the error code when contacting customer support. Error code: 0x80072F76 – 0x20017
The exact same MCT software binary ran well a few days back. Upon investigation, I could see that the problem is at the server end. MCT seems to be unable to download the End-Users License Agreement (Eula) .RTF file from Microsoft’s servers. This is the error seen in setuperr.log

Switching the Internet connection (ISP) did the trick
Thinking that this could be a DNS or ISP related issue, I tried changing to Google Public DNS IPs 8.8.8.8
& 8.8.4.4
, flushed the DNS cache using IPCONFIG
. That didn’t help. However, I switched to another internet connection (provider: BSNL 4G) and the Media Creation Tool could successfully download the EULA this time.

Since my 3G/4G connection is slow here (and mobile data is costly), when compared to my fiber-optic internet connection, I switched over to the original internet connection after the EULA screen was displayed.
So, I hope the issue is only temporary and Microsoft (or perhaps the ISPs) should fix this as soon as possible. Until then, use one of these options:
- Try a different internet service provider. After getting the EULA screen you can switch back to the original internet connection if required.
- Use the Update Assistant tool to upgrade your Windows 10 version.
- Change the browser user agent to iPad (Safari) or mobile, and get the Windows 10 ISO direct download link. See post Get Windows 10 Official ISO Images Using MCT or Direct Download for more details about this method.
Hope the above methods help you resolve error 0x80072f76 - 0x20017
when running the Media Creation Tool.
