Windows 10 Media Creation Tool Error 0x80072f76 – 0x20017

When you run the Media Creation Tool (MCT), you may see the error 0x80072f76 - 0x20017:

There was a problem running this tool.
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

Media Creation Tool: Error 0x80072f76

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:

Hope the above methods help you resolve error 0x80072f76 - 0x20017 when running the Media Creation Tool.
