Windows 7 - Need a Favour?

[katana]

Hi All, I've had to change up to a Windows 10 PC but I have some CAD CAM software that won't work with Win10 so I'm having to create a Virtual Machine inside Win10 to Run Win7. Here is the problem, my old Win7 PC used a pre-installed Dell supplied OS (I have the disc) but to load into a VM I need a Win7 ISO copy (which the disc isn't) and whilst I have the Win7 Key Code, Microsoft won't allow a ISO download using that key ! ! !

So does anyone have a Gen Windows 7 disc - Professional if possible - that they no longer use and that they could give me the MS Key code so I can download the OS ISO - pretty please. I've done a search for OS key codes - there are loads, all of which are blocked by MS so no good. If you can help and don't wish to 'publish' the key here - please send via a PM. 

Thanks in advance for anyone that can assist.
