Hi G,
The error code 715-123130 with the GUID you referenced is not a permanent block but a session or environment failure on Microsoft’s download page. It typically occurs when the request for the ISO is invalidated due to cached cookies, browser extensions, or network routing issues. The ISO files themselves are still available, but the page rejects the confirmation step. The most reliable workaround is to open the page in a clean private/incognito window with no extensions loaded, select the language again, and confirm. If that fails, clear all cookies for microsoft.com and retry, or switch to a different browser. In cases where the ISP or VPN routing interferes, disabling VPN/proxy or trying a different network path usually resolves it.
If none of these work, you can bypass the web form entirely by using the official Media Creation Tool from the same Microsoft download page, which generates the ISO without hitting the 715-123130 error. Microsoft has acknowledged this as a temporary delivery-side issue, so if the problem persists across clean environments, it is best to wait for their backend fix or use the Media Creation Tool as the supported method
Harry.
