How to Install AdiIRC Silently with winget on Windows

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

TL;DR

Open Terminal as Administrator and run:

winget install --id PerAmundsen.AdiIRC -e --silent --accept-package-agreements --accept-source-agreements

AdiIRC: AdiIRC is a free Internet Relay Chat (IRC) client

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

What gets installed

Field	Value
Package ID	`PerAmundsen.AdiIRC`
Publisher	Per Amundsen
Installer type	NSIS (Nullsoft)
License	Freeware
Latest version	4.4
Minimum OS	10.0.0.0
Homepage	adiirc.com

NSIS installers use a single /S flag for silent mode. Add /D=<path> (unquoted, last) for a custom install location.

Per-user install (no admin)

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

winget install --id PerAmundsen.AdiIRC -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 PerAmundsen.AdiIRC -e --version 4.4 --silent

List available versions:

winget show --id PerAmundsen.AdiIRC --versions

Override silent flags

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

winget install --id PerAmundsen.AdiIRC -e --override "/S"

These are the NSIS (Nullsoft)-native silent switches the installer recognises.

Verify after install

winget list --id PerAmundsen.AdiIRC

If the version is shown, the install succeeded.

Upgrade silently

winget upgrade --id PerAmundsen.AdiIRC -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 PerAmundsen.AdiIRC --silent --disable-interactivity

In a provisioning script

PowerShell snippet for unattended Windows setup:

$apps = @(
  "PerAmundsen.AdiIRC"
  # 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

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

winget install --id PerAmundsen.AdiIRC -e --silent --force

"Installer hash does not match" — Per Amundsen 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 — AdiIRC is currently running. Close it then retry. See package in use fix.
