| Issue | Solution |
| :--- | :--- |
| “Fatal Error” on launch | Update Graphics Drivers. Right-click ETABS shortcut → Properties → Compatibility → Run as Windows 8. |
| License manager not found | Reinstall CSI License Manager from the installer’s Tools folder. Check firewall permissions. |
| Model runs slow on 64-bit | Ensure you are using the 64-bit launcher (not accidentally running the 32-bit exe on 64-bit OS). |
| Save fails (disk error) | Run ETABS as Administrator, or change save location to a user folder (not Program Files). |
| Analysis hangs at 90% | Check for unstable model geometry (e.g., unmeshed wall openings). Increase virtual memory. | CSI ETABS 2018 Version 20.2.4.1228 -32-64 Bit- Download
