The License Server is responsible for managing and distributing software licenses. The server regularly checks various technical and organizational requirements. If problems occur, the server returns a specific error code. Each error code is unique and points to a clearly defined cause.

The Error Codes can be divided into seven main categories:

• Server Configuration – covers all problems with the basic infrastructure of the License Server, e.g., missing key files or unsupported encryption methods. These errors usually require intervention by the system administrator.
• Workstation Management – concerns incorrect or incomplete configurations of individual workstations in the system, e.g., missing expiration dates, incorrect versions, or disabled entries.
• License Validation – includes errors that occur when a license has expired, is invalid, or incomplete. This also covers problems with signature verification.
• Computer Registration – refers to the recognition and assignment of hardware to a license. Errors occur if devices are unregistered, blocked, or if too many devices have already been activated.
• File Operations – includes errors that can occur when uploading, saving, or importing License Files, e.g., due to incorrect file formats or insufficient access rights.
• Security & Verification – covers issues related to the verification of hardware IDs, digital signatures, and other security-relevant data in the License File.
• General Operations – describes fundamental errors that cannot be assigned to any of the above categories, e.g., incorrect requests or general creation failures.    

Each category contains multiple Error Codes with different causes. Below is a detailed description of all Error Codes, their causes, and the respective effects.
