The "License Not Recognized Error 30" in ETABS 2016 typically indicates that while a license file was found, it is currently considered invalid by the system. This issue often arises from discrepancies in the system date or corrupted license files. Common Causes of Error 30
System Date Mismatch: If your computer’s date is incorrect, the software may fail to validate the license period.
Expired License: The license may have surpassed its valid duration, causing a validation failure.
Corrupted License File: The lservrc file, which stores the license information, may be incomplete or damaged. Step-by-Step Fixes for Error 30 1. Verify and Sync System Date
The most immediate fix is ensuring your machine's date matches the current actual date.
Right-click the clock in your taskbar and select Adjust date/time.
Ensure Set time automatically and Set time zone automatically are toggled On. Restart ETABS to see if the error persists. 2. Use the "Run As Date" Utility
Many users resolve this by using a third-party utility called RunAsDate. This is particularly common for older versions like ETABS 2016 whose licenses might have a hard-coded expiration. Download and install RunAsDate.
Open the utility and browse for the ETABS 2016 executable (typically in C:\Program Files\Computers and Structures\ETABS 2016).
Set the date to a time when the license was known to be valid (e.g., 2017 or 2018).
Create a desktop shortcut using the utility and launch ETABS through that shortcut instead of the standard icon. 3. Refresh the Standalone License
If you are using a standalone license, it may need to be reactivated:
Navigate to the ETABS installation folder and locate lsdecode.exe. Run it to check your current license type and expiration.
If the license appears invalid, you may need to delete the existing lservrc file in the installation directory and run the activation tool provided by CSI to regenerate it. 4. Check USB Key Drivers (If Applicable) If your license is tied to a physical USB dongle (CID key):
Ensure the Sentinel System Driver is installed and up to date.
Run WechoID.exe in the ETABS folder to confirm your computer recognizes the Computer ID. 5. Network License Troubleshooting
For network-based licenses, Error 30 can occur if the client cannot properly communicate with the server:
Create an LMHOST.INI file in Notepad containing the server’s IP address.
Place this file in the ETABS 2016 installation folder to help the software find the license server faster.
If these steps do not resolve the issue, it is recommended to contact CSI Technical Support for a manual validation of your lservrc file. Are you using a standalone or a network license for ETABS?

In ETABS 2016, Error #30 typically indicates that the software found a license file, but it is considered invalid or corrupted. This guide provides a systematic approach to resolving the issue based on official CSI Knowledge Base recommendations. 1. Verify System Date and Time
The most common trigger for Error #30 is an incorrect system date. If your computer's clock is set to a date before the license was issued or after it expires, the license will be flagged as invalid.
Ensure your system date, time, and time zone are set correctly to the current date. 2. Refresh Licensing Files
If the date is correct, the existing license file (lservrc) may be corrupted.
Locate the file: Go to the ETABS 2016 installation folder (usually C:\Program Files\Computers and Structures\ETABS 2016).
Rename/Backup: Find the file named lservrc and rename it to lservrc_old.
Re-activate: Run the CSiLicensing tool found in the product subfolder to re-enter your activation key and generate a fresh license file. 3. Check for Expired Trial Licenses
An old trial license still residing in the system can sometimes conflict with a new commercial license.
Run the WlmAdmin.exe utility (usually found in the Sentinel RMS License Manager folder). The "License Not Recognized Error 30" in ETABS
Expand Subnet Servers, right-click the old or expired license feature, and select Remove Feature. 4. Reinstall Sentinel System Drivers
If you are using a standalone USB key (dongle), the computer may not be recognizing it correctly.
Verify recognition: Run WechoID.exe in the ETABS folder. If the "Computer ID" box is grayed out, the driver is missing or broken.
Manual Install: Navigate to the KeyDriver folder within your ETABS installation directory and run the Sentinel System Driver installer. 5. Administrative Rights and Compatibility
Run as Administrator: Right-click the ETABS 2016 shortcut and select Run as Administrator. Some licensing components require elevated privileges to read the registry or system files.
Clean Installation: If the error persists, it may be due to corrupted registry entries. Perform a clean uninstall of ETABS, reboot, and reinstall the software.
Note for Network Licenses: If you are on a network, ensure the client machine can reach the server. You can create an LMHOST.INI file containing the server's IP address and place it in the ETABS installation folder to speed up the license discovery.
If none of these steps work, you should contact CSI Support with your lservrc file and a screenshot of the error to determine the exact cause of the invalidity. Licensing errors generated when running CSI software

The License Not Recognized Error 30 in ETABS 2016 typically indicates that the software has found a license file, but it is considered invalid or expired. This often stems from a mismatch between the current system date and the license's hardcoded expiration date or an incorrect regional date/number format. Primary Troubleshooting Steps
Verify System Date and Time: Ensure your computer's date and time are accurate. If the license is expired, some users temporarily fix this by setting their system date back to a period when the license was active (e.g., early 2018 or 2015).
Change Regional Date Format: CSI software can be sensitive to regional settings. Change your PC’s date and number format to US (English) mm/dd/yyyy through the Control Panel to resolve potential recognition issues.
Use "Run As Date" Utility: To avoid changing your entire system's clock, you can use the RunAsDate utility to launch ETABS with a specific historical date that matches your license.
Check lservrc License File: Confirm the lservrc file is located in the root installation directory (e.g., C:\Program Files\Computers and Structures\ETABS 2016). If you have a valid license, send this file to CSI Technical Support to determine why it is being flagged as invalid. Service and Administrative Fixes
Restart Sentinel RMS License Manager: If using a network license, ensure the Sentinel RMS License Manager service is "Started" in Control Panel > Administrative Tools > Services.
Run as Administrator: Ensure you are launching ETABS with Administrative privileges, as the licensing engine often requires elevated permissions to access system folders.
Antivirus Exclusions: Temporarily disable your firewall or antivirus to see if they are blocking the licensing service. If this works, add an exclusion for ETABS.exe and the license manager components.
For further assistance, you can refer to the official CSI Knowledge Base for detailed resolution steps on common licensing errors.

Check System Date and Time: Ensure your computer's date, time, and time zone are correct. An incorrect date is a primary cause for Error 30.
Verify Date/Number Format: CSI licensing can sometimes be sensitive to regional settings. Try changing your Windows date/number format to US (English) or mm/dd/yyyy to see if it resolves the validation error.
Run as Administrator: Right-click the ETABS 2016 shortcut and select Run as Administrator. Licensing activation and validation often require elevated privileges that standard user accounts lack. Technical Troubleshooting
UUID Validation: In some cases, the error occurs because the computer lacks a valid UUID. To check this, open the Command Prompt and run: wmic csproduct get uuid. If the output is FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF, the software may not be able to lock the license to your machine. Clean Reinstallation: Uninstall ETABS 2016 and any related Sentinel drivers. Reboot your machine to clear temporary registry entries.
Reinstall the software, ensuring you have administrative rights during the process. Invalid or Corrupted License File : The license
Deactivate and Reactivate: For standalone licenses, try deactivating the license through the Help > License Information menu (if accessible) or the standalone licensing tool, then reactivating it with your original activation key. Official Support Resources
