How to Install 3CX Silently with winget on Windows

Installing 3CX interactively is fine when you're sitting at the machine. When you're deploying to 50 machines or building a CI image, you want a one-line silent install. Here's how winget does it.

Skip to the command

Open Terminal as Administrator and run:

winget install --id 3CX.Softphone -e --silent --accept-package-agreements --accept-source-agreements

3CX: The 3CX Softphone notifies users in real-time of incoming calls and enables easy call management from their desktop. Users can set their status, view CRM & phonebook entries as well as access their BLF panel for fast…

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

What gets installed

MSIX packages install silently by default through the Windows AppX subsystem.

Per-user install (no admin)

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

winget install --id 3CX.Softphone -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 3CX.Softphone -e --version 20.0.1102.0 --silent

List available versions:

winget show --id 3CX.Softphone --versions

Override silent flags

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

winget install --id 3CX.Softphone -e --override "n/a (MSIX is silent by design)"

These are the MSIX / AppX-native silent switches the installer recognises.

Verify after install

winget list --id 3CX.Softphone

If the version is shown, the install succeeded.

Upgrade silently

winget upgrade --id 3CX.Softphone -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 3CX.Softphone --silent --disable-interactivity

In a provisioning script

PowerShell snippet for unattended Windows setup:

$apps = @(
  "3CX.Softphone"
  # 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

"3CX is already installed" — winget detected the existing install. To force-reinstall over the existing copy:

winget install --id 3CX.Softphone -e --silent --force

"Installer hash does not match" — 3CX Software DMCC 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 — 3CX is currently running. Close it then retry. See package in use fix.
