AssetRipper for Windows

Which Windows build should you download?

For most Windows desktops and laptops with Intel or AMD processors, choose the x64 archive: AssetRipper_win_x64.zip. Windows ARM64 is for a Windows device built around an ARM processor. The processor architecture matters more than the laptop brand, screen size, or Windows edition.

The verified 1.3.14 manifest records the Windows x64 archive at 39.7 MB and the Windows ARM64 archive at 37.9 MB. Both official URLs were checked on August 22, 2026 with a successful response and a ZIP signature. These are release facts, not a promise that every Unity input will load.

How to run AssetRipper on Windows

Download from the official release asset, then extract the ZIP completely to a folder you can write to, such as C:/Tools/AssetRipper. Do not treat the compressed archive as the application folder. Keep AssetRipper.exe beside the native libraries and other files shipped in the same archive.

For the first test, use a small Unity file or bundle that you own or are authorized to inspect. Keep the original input untouched and select a separate output directory. This makes it easier to tell whether a result came from the Windows setup, the selected folder, or the Unity data itself.

If Windows blocks the first launch

A Windows reputation or SmartScreen message is not the same thing as proof that a file is malicious, but it is a reason to verify the source. Check that the download came from the AssetRipper GitHub release, that the filename matches the selected architecture, and that the archive was not replaced by a mirror. Keep normal security controls enabled and use the operating system's ordinary review flow.

If the application opens but the expected data is missing, switch from platform checks to input checks. A wrong folder level, a partially extracted archive, encrypted or custom-packed content, and unsupported Unity data can all look like a Windows failure. Test one known file before loading a large directory.

• Do not disable antivirus protection just to force an unknown build to run.
• Do not delete native libraries from the extracted folder to make it look cleaner.
• Do not treat a successful launch as proof that the selected Unity project is supported.
• Keep the exact version, filename, Windows architecture, path, and warning text in your notes.

Windows checks before an issue report

Before opening an issue, make the test reproducible. Record AssetRipper 1.3.14, the Windows architecture, the exact input type, the folder level you selected, and the output location. A short local path and a small authorized sample are more useful than a full game folder that contains many unrelated files.

Separate a launch failure from a loading failure. If AssetRipper.exe never opens, focus on extraction, architecture, permissions, and the Windows message. If it opens but reports no files or fails during export, keep the platform baseline fixed and investigate the input, dependencies, Unity version clue, memory, and output destination.

• Confirm that AssetRipper.exe is still beside the files shipped in the ZIP.
• Use a writable local output folder with enough free space; avoid a synchronized or protected path during the first test.
• Try one serialized file or bundle before selecting an entire directory.
• Save the smallest useful log or screenshot and remove private project information before sharing it.

Keep the Windows output separate

AssetRipper writes reconstructed projects or selected content into the destination you choose. Use a new output folder rather than writing over the original build. This preserves a clean comparison point when you change one variable, such as the archive architecture, the input file, or the export mode.

A readable export is not automatically complete or reusable. Meshes may need materials, textures, scenes, dependencies, or manual repair. The Windows guide gets the application running; the export guide explains how to choose Unity Project, Primary Content, model, GLB, or a focused content result.
