As of April 2, 2024, Progress Software has discontinued new downloads for Telerik JustDecompile. It is no longer offered or supported as part of the Progress Developer Tools portfolio.
If you are looking for an offline installer, here are your available options based on your current status with the tool: 1. Official Offline Installer (For Existing Users)
If you previously had a Telerik account and downloaded the product, you might still find the installer in your Progress/Telerik Account under "Products & Subscriptions."
MSI/ZIP Files: Historically, Telerik provided standalone MSI or ZIP packages for offline use to avoid issues with web-based installers.
Progress Control Panel: While the Control Panel typically handles online installations, it was often used to fetch individual MSI files for manual distribution. 2. Third-Party Archives (Use Caution) telerik justdecompile offline installer
Since the official site no longer hosts the tool, you can find older versions on reputable software mirrors. Note that these are unsupported by Telerik:
FileHippo: Lists version history including 2018 and 2014 releases.
Download3K: Offers a download for version 2024.2.513.0, though the file size listed may indicate a web stub rather than a full offline installer. 3. Open Source Engine
If you need the tool for development or integration purposes, the JustDecompile Engine remains open-source: As of April 2, 2024 , Progress Software
GitHub Repository: You can access the underlying decompilation engine at the telerik-boneyard/justdecompile-engine repository.
Self-Building: This allows you to build the core functionality yourself using Visual Studio if the standalone UI is unavailable. Recommended Alternatives
Since JustDecompile is retired, you may want to consider these active, free alternatives:
dotPeek: A free .NET decompiler from JetBrains that supports offline installation. Title example: Standardizing
ILSpy: A widely used open-source .NET assembly browser and decompiler.
dnSpy: Excellent for both decompilation and debugging of .NET assemblies. JustDecompile FAQ - Telerik.com
Can decompiled code be directly exported from JustDecompile? Yes. We have "Create Project" from decompiled assembly functionality. Telerik.com
Solution: You mistakenly downloaded the web installer. Look for a file containing _Full, _Offline, or .msi (not Setup.exe).
If you have the .msi offline installer, you can deploy silently:
msiexec /i "Telerik.JustDecompile.2024.1.1.msi" /quiet /norestart
To suppress the license dialog:
msiexec /i "JustDecompile.msi" SKIP_LICENSE=1 /quiet
