Zagens Preview

Windows install guide

Zagens is not code-signed yet. This is normal for an early preview — not a virus warning.

Recommended: zip → Unblock → extract → install

  1. Download the Zagens_*_x64-setup.exe.zip file from the download page.
  2. Right-click the zip → Properties → tick Unblock at the bottom → OK.
  3. Extract the zip (Extract All). Do this only after unblocking.
  4. Double-click Zagens_*_x64-setup.exe inside the extracted folder.
Important: unblock the zip before extracting. Windows otherwise copies the "Mark of the Web" onto the installer.

Alternative: run the .exe directly

  1. Double-click the setup.exe.
  2. When SmartScreen appears, click More info.
  3. Click Run anyway.

Verify integrity (optional)

Each artifact ships with a .sha256 file. Matching hashes confirm the download is intact.

Get-FileHash .\Zagens_*_x64-setup.exe.zip -Algorithm SHA256
Get-Content .\Zagens_*_x64-setup.exe.zip.sha256

System requirements

  • Windows 10 / 11 (x64)
  • WebView2 — auto-installed during setup if missing (network required)
  • Bundled runtime sidecar — no separate Python install

Why unsigned?

Code-signing certificates are costly. For this preview we ship with unblock + checksums. Microsoft Store or Azure Trusted Signing may follow later.
