How to Install 7-Zip ZS Non Darkmode Silently with winget on Windows

If you're scripting a Windows machine setup, 7-Zip ZS Non Darkmode is one of those apps you want installed silently — no installer wizard, no progress dialogs, no "Next, Next, Finish". Here's how with winget.

Skip to the command

Open Terminal as Administrator and run:

winget install --id mcmilk.7zip-zstd-ndm -e --silent --accept-package-agreements --accept-source-agreements

7-Zip ZS Non Darkmode: File archiver with support for Brotli, Fast-LZMA2, Lizard, LZ4, LZ5 and Zstandard

Typical install time: 10–60 seconds depending on installer size.

What gets installed

Generic EXE installers vary — winget install --silent makes a best-effort to pass the right flag.

Per-user install (no admin)

If you don't have admin rights, try per-user scope:

winget install --id mcmilk.7zip-zstd-ndm -e --scope user --silent

If the manifest doesn't have a user-scope installer, winget falls back with an error — in that case you genuinely need admin or use the Access denied fix.

Specify a version

To pin a known-good version (useful for reproducible CI / team standardisation):

winget install --id mcmilk.7zip-zstd-ndm -e --version 25.01 ZS v1.5.7 R4 --silent

List available versions:

winget show --id mcmilk.7zip-zstd-ndm --versions

Override silent flags

If winget's --silent doesn't fully suppress the installer's UI, pass native flags via --override:

winget install --id mcmilk.7zip-zstd-ndm -e --override "varies by vendor"

These are the EXE-native silent switches the installer recognises.

Verify after install

winget list --id mcmilk.7zip-zstd-ndm

If the version is shown, the install succeeded.

Upgrade silently

winget upgrade --id mcmilk.7zip-zstd-ndm -e --silent --accept-package-agreements --accept-source-agreements

Or upgrade as part of a bulk weekly cron — see How to update all Windows apps.

Uninstall silently

winget uninstall --id mcmilk.7zip-zstd-ndm --silent --disable-interactivity

In a provisioning script

PowerShell snippet for unattended Windows setup:

$apps = @(
  "mcmilk.7zip-zstd-ndm"
  # add more packages here
)

    --accept-package-agreements --accept-source-agreements
}

Common errors

"7-Zip ZS Non Darkmode is already installed" — winget detected the existing install. To force-reinstall over the existing copy:

winget install --id mcmilk.7zip-zstd-ndm -e --silent --force

"Installer hash does not match" — Igor Pavlov, Tino Reichardt, Sergey Brester published a new version before the winget manifest updated. Wait ~24 hours or pass --force. See hash mismatch fix.

"Access denied" / 0x80070005 — run Terminal as Administrator. See Access denied fix.

0x80073D02 — package in use — 7-Zip ZS Non Darkmode is currently running. Close it then retry. See package in use fix.
