Hi, good day!
To narrow this down, could you confirm
Are you using Edge, Chrome, or another browser? Have you tried InPrivate/Incognito mode or a different browser?
When you click Download, does absolutely nothing happen, or do you see an error/reference code?
Are you connected through a VPN, proxy, work/school network, or third-party security software?
Does the same thing happen if you try the download from another network, such as a mobile hotspot?
Please let me know which language of the Windows 11 ISO you need (English International, English US, German, etc.). Once you confirm the language, I can provide the appropriate direct Microsoft download link for the x64 ISO.
I look forward to receiving your update and I'm willing to collaborate with you till we resolve the issue. Do keep me informed by clicking "Add comment" below.
