How to Install AVR-GCC Silently with winget on Windows

Need AVR-GCC on a server, golden image, or developer workstation without anyone watching the screen? winget's silent install handles it in seconds. Here's the recipe and the gotchas.

The one-line answer

Open Terminal as Administrator and run:

winget install --id ZakKemble.avr-gcc -e --silent --accept-package-agreements --accept-source-agreements

AVR-GCC: AVR toolchain for Windows by Zak Kemble

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

What gets installed

Field	Value
Package ID	`ZakKemble.avr-gcc`
Publisher	Zak Kemble
Installer type	ZIP archive
License	BSD-3-Clause
Latest version	14.1.0
Last release	6/14/2024
Minimum OS	Windows 10+

ZIP packages extract to a target folder — no installer UI to suppress.

Per-user install (no admin)

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

winget install --id ZakKemble.avr-gcc -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 ZakKemble.avr-gcc -e --version 14.1.0 --silent

List available versions:

winget show --id ZakKemble.avr-gcc --versions

Override silent flags

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

winget install --id ZakKemble.avr-gcc -e --override "n/a"

For this installer type, override flags aren't typically needed.

Verify after install

winget list --id ZakKemble.avr-gcc

If the version is shown, the install succeeded.

Upgrade silently

winget upgrade --id ZakKemble.avr-gcc -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 ZakKemble.avr-gcc --silent --disable-interactivity

In a provisioning script

PowerShell snippet for unattended Windows setup:

$apps = @(
  "ZakKemble.avr-gcc"
  # add more packages here
)

foreach ($id in $apps) {
  winget install --id $id -e --silent `
    --accept-package-agreements --accept-source-agreements
}

Wrap in Task Scheduler for one-shot machine provisioning. See Fresh Windows 11 setup.

Common errors

"AVR-GCC is already installed" — winget detected the existing install. To force-reinstall over the existing copy:

winget install --id ZakKemble.avr-gcc -e --silent --force

"Installer hash does not match" — Zak Kemble 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 — AVR-GCC is currently running. Close it then retry. See package in use fix.
