installer/files for Guitar Rig Pro 7

since I recently switched to another non-windows OS, I cant use my copy of Guitar Rig Pro 7 since I cant use Native Access 2, I wonder if there is a way to ask support to give me the installer or VST itself so I can use it on my computer and DAW without Native Access 2 with using my product key as proof of owner ship, would appreciate if Native Instruments could respond me thanks! :)
