System Requirements License Manager


  • IIS 7.5 or higher
  • .NET 4.0
  • A directory where the server can write to.
  • CPU: at least 1
  • Storage space: at least 100 MB
  • Memory: at least 8 MB
  • OS: any OS that supports .NET 4.0 and IIS 7.5

Warning: Watch out when virtualizing servers. The system key that is generated by the License Manager depends on the hardware. If the License Manager is run on multiple systems, the system key may change and the License Manager may not work anymore.


All clients must have HTTP access to the server.

Warning: Make sure that all HTTP calls can reach the server and are not blocked by a firewall in between. The client is regularly performing an HTTP PUT and firewalls can block this after a few times. As the server is set up in the internal network, it is recommended not to have any firewall in between at all.

Tip: We recommend to reserve a DNS name for the server, for instance This will make it easer to move to another IP address, if required in the future.


For administration, a browser supporting HTML5 is required.
