2.6 Documentary copies. The Client may make copies of the documentation for his own internal use in connection with the use of the Software in accordance with this Agreement, but no more than the reasonably necessary amount. 18.104.22.168 As authorized in a separate purchase document or documentation and subject to the licensing limits set out in this Agreement, the client may install the Software on a server only to allow a person to access and use the Software from a computer located within the same internal network („Network User”). The network user who has access to this software on the server is called the „server software user.” The total number of server software users (not the simultaneous number of users) should not exceed the number allowed. For example, if the client has purchased 10 licenses for software (the authorized number is 10) and the client chooses to install the software on a server, the client can only allow access to the software to 10 server software users (although the client may have more than 10 network users or less than 10 simultaneous users). 2.1.5 Dual Boat Platform. The software is allowed to be used on a specific operating platform. The customer must acquire a separate license to use the software on each operating platform. For example, if the customer wants to install the software on the Mac OS and Windows platforms on a device on which both platforms are run (i.e. a dual-start computer), the customer must first acquire two separate licenses for the software. This also applies when two versions of the software, each developed for a different operating platform, are delivered to the customer on the same medium.
