Windows MSI Installation

Download the latest release

  1. Open the GitHub releases page: Decode-Orc Releases
  2. In the latest release, download the MSI named like Decode-Orc-<version>-windows-x64.msi.

Install from the MSI

  1. Double-click the downloaded MSI file.
  2. Follow the Windows Installer wizard:
  3. Review the license agreement and click "I Agree" to continue.
  4. Choose the installation location (default: Program Files\Decode-Orc).
  5. Select whether to create Start Menu and Desktop shortcuts.
  6. Click "Install" to begin installation.
  7. Wait for the installation to complete and click "Finish".

Unsigned MSI - Additional Steps Required

The MSI installer is unsigned, which means Windows Defender SmartScreen may block installation. Follow these steps:

  1. When you try to run the MSI, you may see a "Windows Defender SmartScreen prevented an unrecognized app from starting" dialog.
  2. Click "More info" to expand the dialog.
  3. Click "Run anyway" to proceed with installation.
  4. The installer will then launch normally.

If you don't see the prompt, you may need to manually disable SmartScreen protection temporarily:

  1. Open Windows Security.
  2. Go to App & browser control.
  3. Under SmartScreen for Microsoft Edge, toggle to Off.
  4. Run the MSI installer.
  5. Re-enable SmartScreen protection after installation.

Option C: Override via Command Line (Advanced)

If the GUI method doesn't work, you can install via PowerShell or Command Prompt:

# In PowerShell as Administrator:
msiexec /i "C:\path\to\Decode-Orc-<version>-windows-x64.msi" /quiet

Replace C:\path\to\Decode-Orc-<version>-windows-x64.msi with the actual path to the downloaded MSI file.

Launching the Application

After installation, you can launch Decode-Orc:

  • Via Start Menu: Search for "Decode-Orc" and click the application.
  • Via Desktop Shortcut: Double-click the "Decode-Orc" shortcut on your desktop (if created during installation).
  • Via File Explorer: Navigate to Program Files\Decode-Orc\bin\ and double-click orc-gui.exe.

Using orc-cli from the command line

The command-line tool orc-cli is included in the installation. You can run it from the Command Prompt or PowerShell:

"C:\Program Files\Decode-Orc\bin\orc-cli.exe" --help

To use orc-cli from any directory, add the installation directory to your system PATH:

  1. Press Win + X and select System.
  2. Click Advanced system settings.
  3. Click Environment Variables.
  4. Under System variables, select Path and click Edit.
  5. Click New and add: C:\Program Files\Decode-Orc\bin
  6. Click OK on all dialogs.
  7. Restart your terminal.

You can then run:

orc-cli --help
