RSA5126B operating system restore image or disk

My RSA5126B hard drive failed totally. I cannot restore the OS from the acronis image since the hadr drive is toast. Is there an OS system restore CD or can someone send me an image?
After installing a new hard disk I have tried installing a win10 IOT 2016 LTSB and then the RSA5100_3_23 instrument software from the Tek site. The software starts but the license is not working of course. The only licence that I have is the soft key label on the back of the instrument.
Can any one help?

Hi Adrian, it's not possible to share the OS Image outside Tektronix.<br> The RSA will need to be Serviced by us for restoringwith the original Windows 10 version provided by Tek.<br> No other Windows 10 version can be installed, they won't work.
