Installation of SFOS Software Installation on SG/XG Hardware

Software Installations require a special license. You need to purchase a base license to use SFOS software installation. If you use the hardware installer for SG/XG/XGS, it already include the base license. 

My questions specifically points to, wheter it is/should be possible, or not. Licensing is another part.

As you have to purchase a new license, it does not make sense to install software installation ISO on the hardware. 

Hardware ISO include different drivers for the own hardware. For example the interface panel on the hardware is not supported on the software installation. 

Ok, thanks for your hints. I already have a software license, that I want to use now. Maybe you can read my question carefully, I am also refering to the old post.

You can do it by wiping the disk and installing it on the hardware, as the hardware is X86 based. It does not make sense to me and can confuse the ports and do other stuff. There is no reason to do it, as far as i know. 

I want to use an NFR SW unlimited license, it´s available for free to me. And I have old sg135 hardware without a license. That´s the reason for why I´m doing this. I was told, that this software licences cannot be bound to hardware installations. That´s the thing.

But the issue is, that I cannot install the software, I get this message:

There are manuals how to do this by other user. You can find this online in this community. 

PS: You can also request a NFR License for the SG135, as far as i know.
