Remediation Steps

• Restart license manager service and, if safe, reboot the license server.
• Replace or reissue license file if corrupted or expired (contact vendor/reseller for a new license).
• Update license manager to a version compatible with your CADWorx client; apply vendor patches.
• Correct environment variables: set LM_LICENSE_FILE or vendor-specific variable to the correct server:port or license file path. Example:

  LM_LICENSE_FILE=@licenseserver.example.com
  

• Adjust firewall rules to open required TCP ports (commonly 27000–27009) and allow the license manager executable.
• Run CADWorx as an administrator and ensure user account has read access to license file and related registry keys.
• If using floating licenses, ensure the license checkout count is not exceeded; audit current checkouts via the license manager admin tool.
• For VPN/NAT scenarios, use the license server’s IP instead of hostname, or configure split tunneling to allow license traffic locally.
• As a temporary workaround, request a node-locked license for the affected workstation while resolving server issues.
