I installed xPC target 2013 on an old computer and it didn't work. That same computer works fine with xPC 2007.
After this, I installed again xPC 2013 on a newer PC and it worked properly.
My question is, what is the Restriction that does not allowed me to run an 2013 rtt on the older computer?
I am looking for documentation but now everything is related to 2015b.
