Can't activate windows 7 (Windows/system32/slui.exe)
Hi, I've been trying to use my Windows 7 key on this PC but every time I go to control panel and click to activate it gives me the error "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access them" In which I do, I'm the admin.
I'm wanting to install Windows 10 but this is standing in my way...
Help, thanks.
