Hi there, reinstalled quite a few window 8 laptops over the last year or so - no problems until now!

Acer Aspire E15-511-C11F, replacement hard-drive. Installed Windows 8.1 from my generic disc as ive done countless times before. Go to enter and eventually activate the BIOS recovered key and it comes up with "That key can't be used to activate this edition of Windows", and if I try to download Win8 iso via there upgrade/setup exe it comes up with "Product key doesn't work, check and try again".

The Windows is installed as UEFI, and it didn't retrieve the key automatically on installation. Also tried downloading a Windows ISO from there Win8 setup app (both 32/64/8/8.1) and again doesn't consider the key valid.

Any suggestions?

Thanks, James
