INSTALL GUIDE

Install DeepSeek Harness Desktop on Windows

Follow these steps to download, verify, install, and complete your first project task.

Windows SmartScreen More info view for the DeepSeek Harness Desktop installer — SmartScreen example: if it shows an unknown publisher, verify the installer name, download source, and SHA-256 first.

1. Download the Installer

Get the current installer from the Windows download page. The page also lists its version, file size, and SHA-256 for verification.

Open the Windows download page →

2. Verify and Install

Use PowerShell to calculate the installer SHA-256 and compare every character with the download page. Without Authenticode, SmartScreen's unknown-publisher message is a known limitation, not proof that verification is complete.

3. Complete First Launch

Launch the app and wait for the main interface. If it remains on the startup screen, open the log from the system tray and remove secrets or private paths before filing an issue.

4. Open a Project and Start a Task

Choose a project directory, use @ to reference files or earlier conversations, and share screenshots with models that support images. File changes, command output, and generated content stay in the workspace so you can keep iterating.
