How do I install software in pc?

[SSB]

Hello, I'm new in this world.

I'm trying to use LM in my pc, but actually I only can use the demo in the page.

I would like if it's necessary to have the LM product in my house to use "the private space".

I need to programme LM with KNX, Modbus, BacnetIP... but I need to know if I can use or privatize the demo, or how to install the software (if exist it) in my pc.

Thanks,
My best regards,
SSB.
