We have now released Corridor EZ v27.02. This release includes an important compatibility update for customers running the latest versions of Civil 3D 2025 or 2026.

Why is this update happening?

Autodesk recently updated its 2025 and 2026 product lines to transition to the Microsoft .NET 10 runtime environment. Because this changes underlying system components, it impacts how older Corridor EZ settings files are handled, particularly settings migrated forward from legacy versions of Corridor EZ.

Do I need to update?

If you are running Civil 3D (versions 2025 or 2026), type ABOUT into your command line to check your current build. If your version matches or is newer than the builds listed below, you must update to Corridor EZ v27.0.2 to maintain compatibility:

  • Civil 3D 2025: Version 2025.2.7 or higher

  • Civil 3D 2026: Version 2026.2.2 or higher

What do I need to do?

To ensure a smooth transition, please install the updates in this specific order:

  1. Ensure your Civil 3D has the latest Autodesk updates installed (matching the version numbers above).

    You can access your Autodesk product updates by visiting https://www.autodesk.com/au/account/home-v2 and entering your Autodesk account details. Then click on Products and Services, then Product Updates to download and install the latest updates for your Autodesk product/s.

  • Robust Settings Migration: Improved stability when carrying forward older project and application settings.

  • Smarter Error Handling: Suppressed unnecessary warnings if a legacy setting cannot be converted.

  • Advanced Diagnostics: Improved logging to help our team troubleshoot migration edge cases quickly.

  • New Features and Enhancements: This update includes a number of new features, fixes and enhancements to improve your day-to-day operations. Learn more https://corridorez.com/whats-new/corridor-ez-v27-02-release-notes/
