The "story" of the Telerik JustDecompile offline installer has reached its final chapter. For over a decade, it was a staple for .NET developers, but as of April 2, 2024, Progress Telerik officially retired the product.
Here is the timeline of how the "updated" offline installer journey evolved and ultimately ended: 1. The Glory Days: "Fast and Free Forever"
Released around 2011, JustDecompile was marketed as the "fastest decompiler," often claiming to be 10x faster than its competitors. It was a free alternative to tools like .NET Reflector, which had shifted to a paid model. For years, the offline installer was the gold standard for developers working in secure environments or on machines without constant internet access. 2. The Final "Update" (Version 2024.1.131.0)
The last significant update to the offline installer addressed a critical security vulnerability (CVE-2024-0219), which could allow privilege elevation.
The "Latest" Version: Telerik confirmed that 2024.1.131.0 is the absolute final version of the tool.
No More New Versions: There are no planned updates for 2025 or 2026. The official Telerik Release History for 2026 shows updates for products like Fiddler and UI for Blazor, but JustDecompile is notably absent. 3. Retirement and the "Boneyard"
In April 2024, Progress Software stopped offering new downloads of JustDecompile.
Current Status: If you already have the offline installer, you can keep using it indefinitely, but you can no longer download it from the official Telerik site.
The Open Source Legacy: While the UI is closed, the underlying JustDecompile Engine was open-sourced under the Apache 2.0 license. However, its official GitHub repository has been moved to the "boneyard" and hasn't seen major activity in years. 4. What Now?
Since the official offline installer is no longer updated or available for new users, Telerik and the developer community suggest these alternatives: The Story Behind JustDecompile - Telerik.com
Telerik JustDecompile was officially retired as of April 2, 2024, and as of 2026, it is no longer actively maintained or supported by Progress Telerik. The final stable release of the software is version 2024.1.131.0, which was released in late 2024 to address a specific privilege elevation vulnerability (CVE-2024-0219). Offline Installer Availability telerik justdecompile offline installer updated
While Progress Telerik has discontinued new official downloads of the standalone tool, users who already have it can continue using it indefinitely.
Final Version: 2024.1.131.0 (some third-party mirrors like FileHorse may list slightly different build numbers like 2024.2.513.0, but the core engine development has ceased).
Offline Packages: Historically, Telerik provided MSI or ZIP files for offline installation, but these are no longer easily accessible via the official website's primary navigation.
Third-Party Mirrors: Repositories such as FileHorse and CNET Download currently host the latest installer (approx. 4.33 MB), though use caution with third-party sites. 2026 Review & Assessment
Despite its retirement, JustDecompile remains a lightweight and capable tool for older .NET projects. Pros:
Performance: It is noted for high decompilation speed, often outperforming older paid competitors.
Features: Includes "Create Project" functionality, which attempts to rebuild a full Visual Studio project from a decompiled assembly.
Legacy Support: Excellent for .NET Framework (2.0–4.5), Silverlight, and WinRT metadata files. Cons:
No Modern Updates: It does not receive official support for the latest .NET versions (e.g., .NET 8/9/10).
Vulnerability Risks: While the final version fixed CVE-2024-0219, no future security patches will be issued.
Limited Ecosystem: The official plugin manager and engine are largely static or moved to community-driven forks like CodemerxDecompile. Recommended Alternatives
Since JustDecompile is no longer evolving, most developers in 2026 have moved to the following free, actively maintained tools:
ILSpy: An open-source .NET decompiler that frequently updates for the newest .NET releases.
JetBrains dotPeek: A free standalone tool from JetBrains that offers advanced features and tight integration with other developer workflows. NET 9 or 10 frameworks? AI responses may include mistakes. Learn more JustDecompile - Download for Windows - FileHorse
Still Going Strong: Getting the Telerik JustDecompile Offline Installer (2026 Update)
If you have been a .NET developer for a while, you know that Telerik JustDecompile was the go-to tool for fast, reliable assembly browsing. While Telerik officially retired the product on April 2, 2024, many developers still rely on it for legacy projects and quick code analysis.
The challenge? Since the official "future downloads" have been discontinued from the primary product page, finding a reliable offline installer (MSI or ZIP) is now a bit of a treasure hunt. Why You Still Need an Offline Installer
In 2026, many development environments are strictly firewalled or air-gapped for security. Relying on an online "web installer" is no longer an option for many enterprise teams. Having an offline installer ensures you can: Install without an internet connection on secure servers.
