Software Installation

my customer bought from you ip-symcon program - at my request
I have to prepare for him a system of visualization.
I have a link to the software.
The following steps must enter the activation coda. Of course, we received
this code when purchasing.
Question (and our fear) is as follows:
Does the software can be installed on any computer on several occasions?

The first installation will be on my computer - developer
The second installation will be on the target computer - client
