Quartus 26.1 only supported in Windows 11 check this https://www.altera.com/design/guidance/software/os-support
Could you try uninstall and re-install?

Here I am just using System-Console. The requirements should be loser that full Quartus, though I couldn’t find a page for it.

thanks for pointing the requirements to Quartus 26.1, shouldn’t OS-validation be enforced at installation? I’m assuming I’m not the only one who spend days troubleshooting, and forgot to check if Windows 10 support was discontinued

I would suggest try to uninstall and re-install. Before re-installing, make sure turn off any suspicious software like anti-virus, anti malware or vpn
