Once you have the correct offline MSI file, installation is straightforward:
No internet connection is required after this point – the decompiler works entirely offline.
Progress Software (owner of Telerik) still maintains JustDecompile, but the free edition is no longer a priority. Most active development focuses on their commercial decompiler inside Fiddler Everywhere and Test Studio. The standalone free JustDecompile receives only critical updates.
If you need an offline installer for a specific version (e.g., 2020), your best bet is to ask on Telerik’s official forums or support if they’ll provide a legacy link. Sometimes support will give you a direct URL if you explain a valid use case (air-gapped network, corporate policy). They are surprisingly helpful when you don’t ask for a crack.
So, after this long story, here’s my advice:
I cannot and will not give you a direct download link to an unauthorized offline installer. That would hurt both you (security risk) and the software maker (piracy).
Telerik JustDecompile: Finding an Offline Installer and Why It Matters
In the world of .NET development, having a reliable decompiler is essential for debugging third-party libraries, recovering lost source code, or simply understanding how a specific assembly functions under the hood. Telerik JustDecompile has long been a favorite due to its speed and the fact that it is offered for free.
However, many developers working in secure environments or with limited connectivity often search for a Telerik JustDecompile offline installer link. This guide explains how to get the installer, why you might need the offline version, and how to manage your installation. Why Use an Offline Installer?
While web installers are convenient for users with high-speed, constant internet access, the offline installer (often referred to as a "standalone" or "full" installer) offers several advantages:
Air-Gapped Environments: Many enterprise or government development environments are restricted from the public internet for security reasons.
Deployment Efficiency: If you need to install the tool on multiple machines, downloading a single large file once is faster than running a web stub on every station.
Archiving: Keeping a specific version of a tool on a local drive ensures you can reinstall it even if the vendor updates the software or changes their distribution model. How to Get the Telerik JustDecompile Offline Installer
Telerik (now part of Progress) typically manages their downloads through a centralized account system. To get the latest version of the offline installer, follow these steps:
Visit the Official Site: Go to the Telerik JustDecompile product page.
Log In or Sign Up: You will likely need to create a free Progress Telerik account.
Navigate to Downloads: Once logged in, go to the 'Your Account' section and find 'Downloads'.

Create Visual Studio Projects: One of its most powerful features is the ability to export a decompiled assembly as a full Visual Studio project (.csproj). Safety Warning Regarding Third-Party Links

It is highly recommended to only download the installer from the official Progress Telerik website.

Explain the differences between the available .NET decompilers.
While Telerik JustDecompile is a powerful, free tool for recovering lost source code and browsing .NET assemblies, finding a direct "offline installer" link can be a bit of a treasure hunt. Unlike many standalone utilities, Telerik primarily distributes its software through its own ecosystem.
Here is everything you need to know about getting the JustDecompile offline installer and why it’s the preferred choice for many developers. Why Use a Telerik JustDecompile Offline Installer?
Most developers initially encounter the online installer—a small file that downloads the rest of the program during the installation process. However, the offline installer (or "standalone installer") is often more desirable for several reasons:
Air-Gapped Environments: Many corporate or high-security development environments do not have open internet access.
Unstable Connections: If your office Wi-Fi is spotty, the online installer may fail halfway through a 100MB+ download.
Archival Purposes: Keeping an offline .msi or .exe in your "Dev Tools" folder ensures you can reinstall the tool years from now, even if the official download page changes. How to Get the Official Telerik JustDecompile Offline Link
Telerik (now part of Progress) requires a free account to access their downloads. To get the most current, secure, and "clean" version of the offline installer, follow these steps: 1. The Official Telerik Account Portal (Recommended)
The safest way to get the offline installer is through the Progress Telerik backend: Go to the Telerik JustDecompile Product Page. Click on Download Free Tool. You will be prompted to log in or create a free account.
Once logged in, navigate to the 'Your Account' > 'Downloads' section.
Look for JustDecompile in your list of products. There is usually a toggle or a link labeled "Browse all product files" or "Manual Installation". This is where the standalone .msi offline installer is hosted. 2. The Progress Control Panel
If you already use other Telerik products (like Kendo UI or Telerik Reporting), you likely have the Progress Control Panel installed. Open the Control Panel. Find JustDecompile.
Check the settings to "Download installers locally." This will save the full offline setup file to your computer. What if I Can’t Access the Telerik Account?
While there are third-party software mirrors (like MajorGeeks or Softpedia) that host JustDecompile, be cautious. These sites often host older versions that may not support the latest .NET 6, 7, or 8 assemblies.
Always check the digital signature of the file after downloading from a third party. Right-click the installer > Properties > Digital Signatures. It should explicitly say "Progress Software Corporation" or "Telerik AD." Key Features of JustDecompile
Once you have used your offline installer to get the tool running, here is what you can do with it:
Fast Decompilation: It is widely considered one of the fastest decompilers on the market, rivaling tools like ILSpy and dotPeek. Click Install
Extensibility: It supports a robust plugin API. You can add features like the "Reflexil" plugin to edit assemblies directly.
Create Visual Studio Projects: One of its best features is the ability to take a compiled .dll and export it as a full .csproj that you can open and debug in Visual Studio.
Command Line Support: Perfect for automating code analysis within a CI/CD pipeline.

Visual Studio Project Creation: You can export an entire decompiled assembly into a Visual Studio Project (sln/csproj), making it easy to rebuild lost projects.
One-Step Usage Analysis: Unlike other tools that require multiple steps, JustDecompile allows you to see all "used by" and "instantiated by" references in a single step using Ctrl + Click.
Command Line Support: It supports bulk decompilation via the command line, which is useful for automation and scripts.
Deobfuscation Support: By integrating the De4dot extension, it can decompile assemblies that have been obfuscated.
