Covadis 171h Fix
Q: Can I fix a Covadis 171h without soldering? A: Rarely. Only if the fix is external (wiring, power supply, or configuration). Most internal fixes require soldering new capacitors or transceivers.
Q: How long does a typical 171h fix take? A: External fixes: 15-30 minutes. Internal hardware repair: 1-2 hours. Firmware reflash: 30 minutes plus tool setup.
Q: The error code 171h flashes only when the system is hot. What does that mean? A: Classic sign of thermal intermittent failure. Replace C8, C11, and C14 (the electrolytic capacitors nearest the voltage regulator). Also reflow solder on the main IC.
Q: Is there a known factory recall for Covadis 171h? A: Check the serial number range. Units manufactured between week 22 of 2018 and week 14 of 2020 had a batch of counterfeit capacitors. Those are high-priority for the 171h fix.
Q: My repaired unit works but has a 1% offset error. How do I fix that? A: After capacitor replacement, the reference voltage often shifts slightly. Perform the full recalibration described in Phase 3, Step 8. Do not attempt to compensate with software trimming alone.

The Covadis software platform—widely used in surveying, engineering, and civil design (often alongside AutoCAD)—can occasionally throw an error, commonly referred to as Error 171h (often displayed as [171h] or a similar identifier).
This error typically indicates a hardware lock (dongle) incompatibility, a missing driver, or a compatibility issue between the specific Covadis version and the installed Windows operating system. The Story of the "Fix" (171h)
Imagine a busy civil engineering firm on a Friday afternoon, with a major project deadline due in two hours. A lead surveyor opens Covadis to generate a 3D terrain model, but instead of the loading screen, a harsh, unexpected dialog box appears: [171h]. The software refuses to open. The panic sets in—the digital key to the software is not being "seen." 1. The Immediate Investigation
The first step in the "fix" isn't a complex code rewrite, but a physical one.
The Dongle Check: The user immediately checks the USB dongle (the hardware license key). Is it plugged in? Is it glowing? covadis 171h fix
Re-seating the Lock: Simply unplugging the USB dongle and plugging it back into a different USB port can sometimes reset the handshake between the computer and the license, instantly fixing the 171h error. 2. The Driver Solution (The Most Likely Culprit)
If re-seating doesn't work, the issue is almost certainly the driver software that allows Windows to talk to the USB dongle.
The Fix: The engineer needs to install or update the HASP/Sentinel drivers. These drivers are essential for managing the licensing key. Actionable Step:
Go to the SafeNet/Thales Sentinel website to download the latest Sentinel HASP/LDK Windows GUI Runtime Installer.
Uninstall the old driver, restart the computer, and install the new driver. Restart again. 3. The Compatibility Fix
If the drivers are up to date, the issue might be Windows compatibility.
The Fix: Right-click the Covadis/AutoCAD shortcut -> Properties -> Compatibility -> Select "Run this program in compatibility mode for" and choose Windows 7 or Windows 8.
Run as Administrator: Ensure the application is allowed to run as an administrator to bypass permission issues that might stop the license check. 4. The Last Resort (Version Update)
If none of the above work, it is possible the 171h error is arising because the user is trying to run an older version of Covadis on a newer version of Windows, which no longer supports the older license key type. The fix then becomes a necessity to upgrade the software to a modern version. Summary Table: 171h Fix Steps Potential Outcome 1 Re-seat USB Dongle Immediate fix if it was just a loose connection. 2 Update HASP Driver Solves 90% of 171h errors caused by OS updates. 3 Compatibility Mode Fixes issues with older Covadis on new Windows. 4 Check Firewall/AV Sometimes security software blocks the key.
The "171h" error is usually a temporary roadblock, not a permanent failure, often resolved by updating the USB driver. If you'd like, I can: Q: Can I fix a Covadis 171h without soldering

There is no "paper" in the sense of a scientific journal or general publication for this specific fix. Typically, such "fixes" are provided as technical patches or hotfixes directly by the software developer, Geomedia. Where to Find Official Support
Customer Portal: Authorized users can download the latest patches and version 17.1h updates directly from the Geodesial Customer Support Portal.
Update Logs: Detailed documentation of what version 17.1h fixes (such as compatibility issues with newer AutoCAD versions or specific calculation bugs) is usually included in the "Readme" or "What's New" file within the installer package. Important Note
If you are looking for a "crack" or "bypass," please be aware that using unauthorized software patches can compromise your system's security and lead to unstable project data. It is always recommended to use official versions for professional engineering and surveying work.

While the spindle is out, replace the bearings. Even if they feel okay, if they have 20+ years of use, they are living on borrowed time.
Order a Covadis 171h Rev 2 or later revision. These often have improved power supply filtering and conformal coating. Transfer your configuration parameters manually or via the software backup.
Once the spindle is on the bench, you will see the drawbar assembly.
