License Operation and Availability

When a user starts an Autodesk product, the product determines the server from which it should try to obtain a license. The product then requests a license through the TCP/IP network protocol to the license server.

If the number of available licenses has not been exceeded on the license server, the Network License Manager assigns a license to the workstation. A product session then starts on the workstation, and the number of available licenses on the license server is reduced by one.

Likewise, when a user exits a product, the Network License Manager frees a license for another user. If a user runs multiple sessions of an Autodesk product on an individual workstation, only one license is used. When the last session is closed, the license is freed.

The following three processes manage the distribution and availability of licenses:

NoteIf the adskflex.exe vendor daemon terminates for any reason, all users lose their licenses until lmgrd.exe restarts the vendor daemon or the problem causing the termination is resolved.
