This often happens due to registry corruption during installation, changes in system hardware IDs, or outdated license management tools. Common Causes of Error 18
Corrupted License File: The lservrc file (or similar license markers) may be damaged or missing from the installation directory.
Registry Issues: Conflicts in the Windows Registry can prevent the software from properly communicating with the Sentinel RMS License Manager.
Hardware Changes: Because licenses are often locked to specific hardware (like Ethernet Address or CPU ID), updating drivers or changing hardware can invalidate the existing license.
Version Mismatch: Using an older Sentinel RMS License Manager that does not recognize newer v18 licenses. Step-by-Step Solutions 1. Regenerate and Replace the License File
If the license is corrupted, you may need to manually place a fresh license file in the correct folders. Locate your license file (typically named lservrc).
Copy and paste it into the SAP2000 installation folder (e.g., C:\Program Files\Computers and Structures\SAP2000 18).
Also place a copy in the CSI Licensing subfolder within that directory. 2. Refresh the Native Image
