Related issue: Fixes the nightly ingest-maintained-apps failure: panic: ingesting winget app: failed to find installer for app on Audacity.

What changed

Audacity 4.0.0 landed in winget on 2026-09-03 and the vendor replaced the Inno Setup exe with a WiX MSI (x64 and arm64 only). Our input was pinned to installer_type: exe, so no installer matched and the whole ingest run died.

  • inputs/winget/audacity.json: installer_typemsi, add program_publisher: "Audacity".
  • scripts/audacity_install.ps1: install the MSI per-machine with ALLUSERS=1, then remove any legacy Audacity 3.x Inno install after a successful install.
  • scripts/audacity_uninstall.ps1: remove every product under the Audacity 4 UpgradeCode, then any legacy 3.x install the older FMA deployed.
  • pkg/patch_policy/patch_policy.go: open-query override matching both audacity.exe and audacity4.exe.
  • outputs/audacity/windows.json: regenerated to 4.0.0.

Why each piece is needed (verified with msiinfo against the downloaded MSI)

  • Publisher: the winget locale still says Audacity Team, but the MSI Manufacturer (what osquery reports) is Audacity. Without program_publisher the generated exists query never matches.
  • ALLUSERS: the MSI Property table has no ALLUSERS, so Fleet's SYSTEM-context msiexec /i would register per-user in the SYSTEM profile.
  • Process name: the executable is now Audacity4.exe, so the default <name>.exe open-query guess is wrong.
  • Side-by-side install: Audacity 4 installs to %ProgramFiles%\Audacity 4 with a new UpgradeCode and cannot remove the Inno product. Left alone, 3.x stays behind and is invisible to the new publisher-filtered queries, so it would never be patched. Removal runs only after the MSI install succeeds, so a failed install leaves the old app working.

Reviewer notes

  • Removing 3.x during the 4.0 install is a deliberate call. Audacity 4.0 is missing some 3.x features (macros, MIDI tracks, mixer). If we'd rather leave 3.x in place, drop Remove-LegacyAudacity3 from the install script.
  • The validator's version check is prefix-based, so the registry 4.0.0.262451524 matches 4.0.0; use_display_version_for_patch is not needed.
  • The SHA in the output matches the MSI hashed locally.
  • No changes file: FMA catalog updates are not user-facing release notes.

Checklist for submitter

  • Input data is properly validated, SELECT * is avoided, SQL injection is prevented (using placeholders for values in statements), JS inline code is prevented especially for url redirects, and untrusted data interpolated into shell scripts/commands is validated against shell metacharacters.
  • Timeouts are implemented and retries are limited to avoid infinite loops

Testing

  • Added/updated automated tests — existing ee/maintained-apps/ingesters/winget, pkg/patch_policy, and cmd/maintained-apps/... tests pass.
  • QA'd all new/changed functionality manually — relies on the Windows FMA validator in CI; PowerShell is not available locally to exercise the scripts.

Summary by CodeRabbit

  • New Features

    • Updated the Windows Audacity package to version 4.0.0 using the new MSI installer.
    • Added support for detecting and managing both Audacity 4 and legacy Audacity 3 installations.
    • Added handling for Audacity processes under both executable names.
  • Bug Fixes

    • Improved installation and uninstallation reliability, including restart-required success states and timeout handling.
    • Audacity 3 installations are now removed during Audacity 4 installation or uninstallation.

Audacity 4.0.0 replaced the Inno Setup exe with a WiX MSI, so the input
pinned to installer_type exe matched no installer and the nightly ingest
panicked. Switch to msi, set program_publisher to the MSI Manufacturer
("Audacity", not the stale locale "Audacity Team"), install with
ALLUSERS=1 since the MSI does not set it, remove the side-by-side legacy
3.x Inno install after a successful install, and match the renamed
Audacity4.exe process in the open query.

🟡 Changes recommended

The legacy 3.x removal logic incorrectly parses registry UninstallString values (and the install script can succeed despite legacy uninstall failures), which can leave hosts in the intended “side-by-side” state indefinitely.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

Updates Fleet’s Windows Fleet-maintained app (FMA) for Audacity to track the new Audacity 4 WiX MSI in winget, ensuring ingest and patching logic continue working after the vendor switched installer formats and executable naming.

Changes:

  • Switch Audacity winget input to installer_type: msi and set program_publisher: "Audacity".
  • Update install/uninstall PowerShell scripts for MSI install + uninstall via UpgradeCode, and attempt removal of legacy Audacity 3.x (Inno Setup).
  • Regenerate the Windows output manifest to 4.0.0 and add a patch-policy open-query override to match audacity.exe and audacity4.exe.

  • This legacy-removal path logs the Inno uninstaller exit code but does not act on failures, so the script can return success while leaving Audacity 3.x installed (which defeats the stated goal of converging on a single Audacity install). Consider failing the install when the legacy uninstall returns a non-zero exit code.
    $process = Start-Process -FilePath $uninstaller `
        -ArgumentList "/VERYSILENT /SUPPRESSMSGBOXES /NORESTART" `
        -PassThru -Wait -NoNewWindow
    Write-Host "Legacy uninstall exit code: $($process.ExitCode)"

Review Change Stack

Walkthrough

Audacity for Windows now targets version 4.0.0 through a WiX MSI. Detection uses the Audacity publisher, the new version, both process names, and an MSI UpgradeCode. Installation runs the MSI and removes legacy Audacity 3.x installations. Uninstallation removes all related MSI products and then removes any matching Audacity 3.x installation. Process policy now recognizes both Audacity executables.

Merge Risk: 🟡 Moderate · up to 276e5

Audacity 4 installation or removal can report success while Audacity 3 remains installed, particularly when legacy uninstall commands include arguments or cleanup fails. Resolve the cleanup error handling before merge.

Inline comments:
In `@ee/maintained-apps/inputs/winget/scripts/audacity_install.ps1`:
- Line 45: The legacy uninstall path currently only logs a nonzero
$process.ExitCode, allowing the install script to exit successfully. Update
audacity_install.ps1 at the legacy uninstaller handling to throw or exit nonzero
when removal fails, while preserving success behavior for a zero exit code;
regenerate the embedded script in
ee/maintained-apps/outputs/audacity/windows.json at line 22 with the same
failure propagation.

In `@ee/maintained-apps/inputs/winget/scripts/audacity_uninstall.ps1`:
- Line 45: Update the legacy uninstall handling around $uninstaller to parse
UninstallString into a clean executable path and existing arguments before
calling Test-Path, rather than using Trim('"'). Preserve the parsed arguments
when invoking the executable, then append the silent flags so valid uninstall
commands are executed instead of being skipped.
