**Related issue:** Resolves #50332 Adds **TeamViewer Host** as a Windows Fleet-maintained app. ## The issue's premise was wrong — this needed no new capability #50332 was blocked on "not in winget." It is in winget: `TeamViewer.TeamViewer.Host`, published continuously since **June 2023** (v15.42.8), currently **15.80.4** (merged upstream as microsoft/winget-pkgs#409335, 2026-07-29). I downloaded the live x64 installer and its SHA256 matches that manifest byte-for-byte. It reads as absent because it's nested a level deeper than you'd expect — `manifests/t/TeamViewer/TeamViewer/Host/`, a sibling of the full client's *version* directories rather than of the publisher's package directories. Consequence: this comes off the dependency on #50364, and that FR loses one of its three examples. The other two (#50328, #50329, OLE DB Driver 18/19) still hold — there is no OLE DB package under any winget publisher. ## Identity verified against the installer, not winget metadata Per the `new-fma` golden rule, from the x64 MSI's `Property` and `Registry` tables: | Field | Value | Evidence | |---|---|---| | `unique_identifier` | `TeamViewer Host` | MSI `ProductName`; no `ARPDISPLAYNAME`, empty `Registry` table, so this is the ARP DisplayName | | publisher | `TeamViewer` | MSI `Manufacturer`, equal to the winget locale `Publisher` → no `program_publisher` override | | `installer_scope` | `machine` | `ALLUSERS=1` | | bootstrapper? | No | no `ARPSYSTEMCOMPONENT` | Corroborated independently by [silentinstallhq's PSADT script](https://silentinstallhq.com/teamviewer-host-install-and-uninstall-powershell/), which detects the app with `Get-InstalledApplication -Name 'TeamViewer Host'` and uses `/S` for both install and uninstall. Generated exists query: ```sql SELECT 1 FROM programs WHERE name = 'TeamViewer Host' AND publisher = 'TeamViewer'; ``` No collision with the existing `teamviewer/windows` FMA, which generates an exact `name = 'TeamViewer'`. ## Why exe + `ignore_hash`, matching the full client winget offers Host as an NSIS exe and as a nested `wix` MSI inside a zip. The ingester can't select the zip (`installer.InstallerType` is `zip`, which never normalizes to `msi`), so the exe is the only reachable installer. TeamViewer publishes no version-pinned Host exe — `TeamViewer_Host_Setup_x64_15.80.4.exe` and the x86 equivalent both 404 — so the manifest's URL is the unpinned `TeamViewer_Host_Setup_x64.exe` and `ignore_hash: true` is required. This is vendor asymmetry, not a fixable winget defect: the *full* client does publish pinned exe URLs. Same reason `teamviewer/windows` already sets `ignore_hash`. ## Correcting the coexistence note in #50332 The issue assumed Host and the full client can co-exist. They can't. The Host MSI's `LaunchCondition` table blocks the install outright: > Error 25001: An incompatible TeamViewer package was detected that conflicts with the current MSI package: TeamViewer_Full 64-bit. Please manually uninstall this package. …plus equivalents for Full 32-bit/ARM64, Host ARM64, and the NSIS installs. **Relevant to validation: the validator host must not already have `teamviewer/windows` installed.** ## Icons No `index.ts` change needed — `matchLoosePrefixToKey` treats keys as whole words at the start, so `"teamviewer host"` matches the existing `teamviewer` key and inherits the TeamViewer brand icon. Verified against the real 1,163-key map. The website resolves its icon from the slug (`app-icon-${slug}-60x60@2x.png`) with no such fallback, so `app-icon-teamviewer-host-60x60@2x.png` is added — a copy of the existing TeamViewer brand asset, since Host ships the same logo. ## Two things for review 1. **The PowerShell is unverified.** Authored on macOS with no PowerShell available, so install/uninstall have not been executed. The uninstall script searches ARP by DisplayName instead of a hardcoded key, and uses the three-shape `UninstallString` parser (TeamViewer's is unquoted and contains a space in `C:\Program Files\...`, which the older `.Split('"')` approach in `teamviewer_uninstall.ps1` mishandles). Validator run is the real check. 2. **Category mismatch with the macOS side.** This uses `Communication`, matching the merged `teamviewer/windows`. #47121 adds `teamviewer-host/darwin` with `Productivity`. Worth reconciling — and that PR will want this same website PNG, so expect a trivial conflict. `name` is `TeamViewer Host`, matching #47121 so both platforms group together in the FMA library. ## Testing - [x] `go test ./cmd/maintained-apps/... ./ee/maintained-apps/...` passes - [x] Generator is idempotent — re-running produces no diff and preserves the `apps.json` description - [x] `apps.json` is valid JSON with no empty descriptions - [x] Live installer SHA256 confirmed against the winget manifest - [ ] FMA validator: install → detect → uninstall on a Windows host **(pending — needs a host without the full TeamViewer client)** No shared code changed. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5 <noreply@anthropic.com> Co-authored-by: Allen Houchins <allenhouchins@mac.com>

Open-source platform for IT and security teams with thousands of computers. Designed for APIs, GitOps, webhooks, YAML, and humans.
What's it for?
Fleet gives you a single system to secure and maintain all your computing devices over the air. You can do MDM, patch stuff, deploy software, and verify anything, all from one place, across every OS your organization uses.
Fleet works directly with data and events from the native operating system, down to the bare metal. Strong diagnostics let you investigate errors on end-user devices and collect accurate audit evidence in minutes.
Get started
You can try Fleet out for yourself, or grab time with one of the maintainers to chat.
Is it any good?
Fleet is used in production by IT and security teams managing thousands of devices. Many deployments support tens of thousands of hosts, and a few large organizations manage 400,000 or more.
Supported platforms
- Linux (all distros)
- macOS
- Windows
- Chromebooks
- iOS and Android (BYOD or corporate-owned)
- Amazon Web Services (AWS)
- Google Cloud (GCP)
- Azure (Microsoft cloud)
- Data centers
- Containers (kube, etc)
- Linux-based IoT devices
Infrastructure as code
Manage your fleet with GitOps, or use the GUI, REST API, webhook events, and the fleetctl command-line tool.
Linux support
First-class support for all major distros. Linux gets the same attention and visibility as macOS and Windows.
Visibility and compliance
Fleet can report on hundreds of attributes across your devices and ships with CIS benchmarks for macOS and Windows and comprehensive operating system, hardware, and software data. Check out the table reference documentation to see what's available.
Open by design
Fleet is open source and transparent about what it can and can't see. End users can verify exactly how the agent works and what data their company collects. Fleet collects only the data needed to manage and secure devices, not private activity like keystrokes, emails, or webcams.
Good neighbors
Ready-to-use, enterprise-friendly integrations exist for Snowflake, Splunk, GitHub Actions, Vanta, Elastic Jira, Zendesk, and more. Fleet also works with tools such as Munki, Chef, Puppet, Ansible, CrowdStrike, and SentinelOne.
Lighter than air
Fleet is lightweight and modular. You can use it for MDM without using it for security, and vice versa. You can turn off features you are not using.
Free as in free
The free version of Fleet will always be free. Fleet is independently backed and actively maintained with the help of many amazing contributors.
Longevity
The company behind Fleet is founded (and majority-owned) by true believers in open source. The company's business model is influenced by GitLab (NYSE: GTLB), with great investors, happy customers, and the capacity to become profitable at any time.
Fleet Device Management's company handbook is public and open source. You can read about the history of Fleet and our commitment to improving the product.
