1.    If there is a conflict with the default TCP/IP port number (10106), try using another number (refer to the system administrator for assistance).

2.    If the client cannot connect to the floating license server, check that the server and client are connected to the same port.

3. Check the connection back to the Gibbs license database with C:\Program Files\3D Systems\License Server\ activationcheck.exe.

 Sometimes admin accounts don't have internet access for security.


The product supports floating licensing via a TCP/IP port number. This port number (10106) is the default port that is used to communicate between the floating license server and the clients. The server and the clients must be configured to the same port. This means that if you change this port number in the floating license server (via the CimLmService Monitor), you also need to change the port number on the client side (via the License Manager dialog), and vice versa.

Note: The server and the clients must be configured to the same port!!!

3.    If the 3D Systems product is installed on the license server computer and a floating license is used, it should be connected to the server license file in the same way as all other clients ("<Server IP >@<Server Port>").

4.    If the license cannot be found while the product is loading, perform the following:

a.    Check that you entered the correct location of the license file.

b.    If you are on a client computer (floating license), check that you are communicating with the server over the network.

c.    Check that the server license manager has started.

5.    If you encounter a problem with the License Server Monitor (server side), validate that you are an full Administrator with internet access.

6.    Some internet image/sound recorders (e.g. Freecorder from Applian Technologies Inc.) listen to all open ports to intercept transmissions and may cause socket creation problems.
