    Troubleshooting ETABS 2016: Fixing "License Not Recognized" (Error 30)

    Running into Error Code 30 in ETABS 2016 can be a major roadblock for structural engineers. This specific error indicates that while a license was found, it is considered invalid by the system. 1. Verify System Date and Regional Formats

    Because Error 30 often stems from a "validity" check, your computer's internal clock is the first thing the software inspects. Error 30 is a "License Not Found" or

    System Date: Ensure your machine’s date and time are accurate. If your license has a set expiration, even a small discrepancy can trigger Error 30.

    Date Format: Some users found that ETABS requires a specific date/number format to recognize the license properly. Try changing your Windows regional settings to US (mm/dd/yyyy). 2. The "RunAsDate" Workaround

    If you are dealing with an expired standalone license that you cannot immediately renew, many users utilize a utility called RunAsDate.

    How it works: This tool allows you to launch ETABS while "tricking" it into thinking the current date is within the valid license period (e.g., setting it back to 2018 or 2019).

    Crucial Step: You must create a new desktop shortcut through the RunAsDate software for this to take effect. 3. Clean License Re-Activation

    If your license is standalone and appears "incomplete" or corrupted, a fresh activation is often the cleanest fix.

    StandaloneKey.exe: Navigate to the CSiLicensing subfolder in your ETABS installation directory. Use StandAloneKey.exe to deactivate and then reactivate your license.

    Check Locking Codes: Run the echoid.exe or wechoid.exe utilities to ensure your machine's Locking Code matches what is listed in your lservrc license file. 4. Network License Specifics

    If you are on a network license, Error 30 might occur if the client machine cannot communicate effectively with the server.

    LMHOST.INI: Create a file named LMHOST.INI in the ETABS installation folder. Inside, type the IP address or Network Name of the license server to help the software find it faster.

    Sentinel RMS Version: Ensure your server is running Sentinel RMS License Manager 8.6 (or newer, depending on your specific ETABS 2016 build). 5. Advanced System Checks

    To resolve Error #30: License found but license is not valid

    in ETABS 2016, you typically need to synchronise your system's date or re-validate your CSI Knowledge Base Immediate Solutions Check System Date and Time

    : This error often occurs when the system date does not match the period for which the license was issued. Ensure your Windows date, time, and time zone are correct and synced with an internet time server. Run as Administrator

    : Ensure you are launching ETABS with administrative privileges. On newer Windows versions, User Account Control (UAC)

    can block the licensing service from accessing necessary registry keys or system folders. Verify the : Locate the file in the ETABS 2016 installation directory (usually C:\Program Files\Computers and Structures\ETABS 2016

    ). If the file is missing or corrupted, the license will not be recognized. CSI Knowledge Base Advanced Troubleshooting Update Sentinel RMS License Manager : ETABS 2016 specifically requires Sentinel RMS License Manager v8.6 Symptoms of the "License Not Recognized Error 30"

    . If you have an older version, the license will not be recognized. Re-generate the License : If you are using a standalone license, run the ECHODID.exe WECHOID.exe utility found in the installation folder to verify your Locking Code

    . If this code has changed (e.g., due to a hardware change or Windows update), you must contact CSI Support to request a new license file. Remove Trial Licenses

    : If a trial license is still present in the directory, it may conflict with your valid commercial license. Use the WlmAdmin.exe utility to locate and remove any expired "features". CSI Knowledge Base Note for Legacy Installations

    Some users have reported that Error 30 in ETABS 2016 can be bypassed by temporarily setting the system date back to 2015 or early 2016, though this is a temporary workaround and may interfere with other software or security certificates.

    Error 30 in ETABS 2016 is almost always a communication issue rather than a problem with the software itself. In most cases, simply restarting the Sentinel RMS License Manager service or allowing the port through the firewall resolves the problem.

    If you have tried all the steps above and the error persists, it is recommended to generate a diagnostic report using the haspdinst tool or contact CSI Technical Support with your license serial number and computer HostID information for a replacement license file.
