Common problems with network license borrowing for AutoCAD®-based software are listed below. Try applying these solutions first, and then review further instructions if the problem persists.

If these solutions do not resolve the installation error, the additional tests listed below will help you determine the cause of the problem:

  • If you are experiencing problems returning a license from a client machine, you should make sure that the client machine is still pointing to the correct license manager by setting the ADSKFLEX_LICENSE_FILE environment variable. For more information, you should refer to the following solution: Specifying license servers using the ADSKFLEX_LICENSE_FILE environment variable.
  • As a network administrator, consider restricting the maximum borrowing period and/or limiting who in your organization can borrow licenses. These tasks can be performed by implementing an options file on your license manager. For more information, you should refer to the following solution: Controlling network license access using an options file.
