Find out here how your Clients communicate with the Licensemanger

EPLAN Recommendations

• Make sure that all EPLAN clients are in a Windows domain and make sure that you are logged in with a user of the Windows domain.
• If you are working with multiple domains, make sure that you have enabled the Cross-Domain Usage feature.
• Make sure that your firewall does not interfere with communication between the License Manager and the License Client.
• Further information can be found here: ELM_Installation(eplan.help)

We recommend that you carry out these steps together with the EPLAN Consulting Team. Contact us via the contact button on top.
