To avoid losing progress on complex civil engineering designs, maintain your system with these guidelines:

Right-click the desktop shortcut (or the Covadis launcher if using one). Select Properties and navigate to the Compatibility tab. Check the box for Run this program as an administrator . Click Apply and then OK . Fix the Windows Registry Paths Press Win + R , type regedit , and hit Enter.

These errors usually stem from corrupted registry paths, outdated Sentinel HASP driver versions, or strict Windows Defender security blocks. Pre-Requisites Before Applying the Fix

Ensure your base AutoCAD installation is fully updated. COVADIS 17.1h is most stable on AutoCAD 2021-2023.

If your fix package includes a .reg file, double-click it to merge the keys into your Windows Registry. This tells Covadis exactly where to look for its virtual security key. Post-Fix Configuration: Restoring the Covadis Menu

If the fix is applied but issues persist, check the following:

The first and often most effective action is to reset the COVADIS environment. This clears corrupted temporary settings without uninstalling the software. Rather than performing a complete reinstallation—which is time-consuming—this resetting approach is frequently the most efficient solution, validated by technical support teams.

COVADIS 17.1h is a vital topometry and infrastructure design software for AutoCAD. Many surveyors, engineers, and infrastructure designers rely on this specific version for civil engineering projects, road networks, and digital terrain modeling (DTM). However, users frequently encounter installation bugs, licensing errors, and crash loops.
