I misunderstood the features of the free version. The matter is closed.
Thanks for the help.

My native language - Russian. I don`t understand about "top of Hyper-V"

I've done it three times already.

Hi!

During and after installation StarWind Virtual SAN free (version 8 build 7929), the program does not accept 2-node key. 1-node and trial key working.
Cluster of two Windows Server 2012 R2 with Hyper-V role.

How can I install the software?
