So I installed Windows 7 Home Premium onto my PC and it now says that it is not genuine and is asking for a product key that I have since lost. I have a product key for a different version of Windows 7 and when I type it in it says it doesn't work with this version of Windows 7 (because they are different versions I know) and that I should run Windows 7 setup. Is there a way to run Windows 7 setup without the disc?
