The Revit 2020.2.9 Hotfix is the final cumulative update for the Autodesk Revit 2020 product line, released on May 24, 2022. This critical patch addresses security vulnerabilities and stability issues, ensuring that users still relying on this version can maintain a secure and functional BIM environment. Core Updates in Revit 2020.2.9

As a cumulative hotfix, this version includes all previous 2020 updates while specifically introducing the following:

Security Patches: Addresses potential vulnerabilities related to the import of SketchUp files and updates components for importing .adsk files.

Cloud Collaboration: Resolves a major issue where Revit Cloud Worksharing models could fail to open due to missing metadata.

MEP Fabrication: Improves stability when connecting parts that attempt to apply connector adjustments during matching.

Localization: Corrects the Simplified Chinese translation of the "Calculation in Progress" error message. Release Details and Build Numbers Impact and guidance

To verify your installation, check the Help > About dialog in Revit. After a successful update, you should see the following build information: Release Date: May 24, 2022 Build Version: 20.2.90.12 Build Number: 20220517_1515(x64) Installation and Availability

While Revit 2020 is now considered a legacy version outside of Autodesk's standard three-year "previous version" support cycle, the hotfix can typically be accessed via:

Autodesk Account Portal: Log in to your Autodesk Account and navigate to the "Product Updates" section.

Autodesk Desktop App: The update may still appear in the companion app if Revit 2020 is installed.

Deployment Images: Administrators can integrate this hotfix directly into a deployment image for standardized office-wide rollouts. Why This Update Matters

Even if your firm has moved to newer versions, maintaining a patched 2020 environment is essential for archived projects or collaborators using the same version. Specifically, the missing metadata fix for cloud models prevents data loss in older workshared projects. Additionally, users running Revit 2020 on Windows 11 should ensure this hotfix is applied, as it falls under the versions officially supported for that OS.

Impact and guidance

Who should install: Project teams experiencing any of the above behaviors, or users who want the improved stability in linking, annotation, and worksharing. The hotfix is safe for active projects; no file format change is required.
Installation notes: Small installer; apply on machines running Revit 2020.2.x (will upgrade 2020.2.8 to 2020.2.9). Close Revit and all Autodesk background services before installing. Back up critical project files as a precaution.
Rollout recommendation: Pilot on one workstation per team first, then deploy across project machines after validating critical workflows (linking, tagging, sync).

1. Overview

Release Date: October 2022 Build Number: 20200915_1515(x64)

The Revit 2020.2.9 Hotfix was a critical maintenance update released by Autodesk. Because Revit 2020 was a "multi-year" release (supported longer than the standard 3 years due to industry demand), this hotfix addressed specific security vulnerabilities and stability issues that emerged long after the initial launch.

Key Highlights:

Addressed security vulnerabilities within the software.
Fixed issues causing unexpected crashes (especially in specific viewing and printing workflows).
Improved stability when working with third-party add-ins.

Should You Install Revit 2020.2.9? A Decision Matrix

| Scenario | Recommendation | | :--- | :--- | | You are still actively using Revit 2020 for production | YES. The DLL security risk alone justifies the 5-minute installation. | | You only use Revit 2020 to open old archive models, not to edit | Unlikely. If you are only viewing read-only models offline, the hotfix offers minimal benefit. | | Your firm uses a custom plugin that hasn't been updated since 2021 | Test first. Install on a sandbox machine. The 2.9 update may break your workflow. | | You have already upgraded to Revit 2023, 2024, or 2025 | No. Uninstall Revit 2020 entirely to save disk space. Do not maintain a broken 2020 install. |
