UiPath Platform Installer user guide
The UiPath Platform Installer is a lightweight tool that installs UiPath desktop clients and keeps them current through automatic, incremental updates. Instead of redistributing a full installer for every release, it downloads only the changes between versions and applies them in the background.
The installer is small (around 10 MB). After the first installation, it manages the lifecycle of the desktop clients on the machine: checking for new versions, downloading updates in the background, and applying them with minimal disruption.
Supported desktop clients
A single installer maintains the full set of UiPath desktop clients:
- Studio
- Robot
- Assistant
- Delegate
- Browser extensions
Because one installer covers all of these clients, their versions stay aligned and are governed together rather than installed and patched separately.
How it differs from the classic MSI installer
The classic MSI installer (UiPathStudio.msi) remains supported. The UiPath Platform Installer is an additional, continuously updated way to install and maintain UiPath desktop clients, aimed at reducing the effort of keeping them current.
| Aspect | UiPath Platform Installer | Classic MSI |
|---|---|---|
| Update size | Delta — only the changes between versions | Full installer each release |
| Applying updates | Automatic, in the background | Re-run the installer (manually or via SCCM/Intune/scripts) |
| Unattended robots | Updated between jobs, without interruption | Maintenance windows, or risk interrupting running jobs |
| Update governance | Update channel and version, set by policy (IT) | External packaging/scripting, or Orchestrator auto-update |
| Coverage | All desktop clients, including off-Orchestrator, proxy, and internal-mirror machines | Per-product MSI |
For organizations that need it, the two models coexist: a machine can move from the classic MSI to UiPath Platform Installer, and can return to the classic MSI if required.
Benefits
Compared with redistributing the classic MSI for every release, the UiPath Platform Installer:
- Updates unattended robots without interrupting jobs — updates are applied between job executions, so no maintenance window is needed and a running job is never cut off.
- No per-release redistribution — the installer fetches and applies delta updates itself, so IT does not repackage and push a full installer for each release, and each machine downloads only the change between versions.
- Keeps every desktop client in step — one installer maintains Studio, Robot, Assistant, Delegate, and browser extensions at aligned versions, including machines not connected to Orchestrator, behind a proxy, or served from an internal mirror on restricted networks.
- Enforces version control for regulated environments — Enterprise LTS channels let IT pin a maximum version by policy.
UiPath recommends the UiPath Platform Installer for keeping desktop clients current at scale.
How updates work
After the initial install, updates are handled automatically:
- The first installation downloads the full client builds, so it takes longer than later updates.
- For each subsequent release, the installer downloads only the delta — the difference from the installed version.
- Updates download in the background and typically apply within seconds.
There is no automatic downgrade. If an update fails to apply, the machine stays on the previously installed version. If a problem is found after an update succeeds, it is addressed by a newer, fixed version rather than by rolling back.
Update channels
UiPath Platform Installer uses channels to control how updates are delivered. There are three channels:
- Community — the community channel.
- Enterprise STS (Short-Term Support) — the latest features, on a frequent cadence.
- Enterprise LTS (Long-Term Support) — a stable line that receives patch updates only, identified by a version line such as 25.10 or 26.10.
STS and LTS are available only for the Enterprise edition.
For convenience, a dedicated installer pre-selects each channel:
| Installer | Channel |
|---|---|
UiPathPlatformCommunity | Community |
UiPathPlatformSTS | Enterprise STS |
UiPathPlatformLTS-25.10 | Enterprise LTS (25.10 line) |
UiPathPlatformLTS-26.10 | Enterprise LTS (26.10 line) |
Choosing a specific installer is only a convenience for setting the channel up front. The channel can be changed after installation, and the installer updates itself automatically as the desktop clients are updated.
The STS channel is generally available and is covered by this documentation.
Enterprise governance
For enterprise scenarios — particularly long-term support — UiPath Platform Installer is designed to be governed centrally by IT, while the CoE retains visibility into installed versions. Controls include version pinning, channel selection, an internal artifact mirror for restricted-bandwidth environments, and policy-based rollout to groups of machines.
These administrator capabilities are documented in the UiPath Platform Installer admin guide.
Migrating from the classic MSI
When UiPath Platform Installer installs on a machine that already has a classic MSI installation, it is designed to migrate the existing setup and preserve settings, so end users do not need to take action. Reverting to the classic MSI is done by uninstalling UiPath Platform Installer and reinstalling with the classic MSI. For details, see Migrate from the classic MSI.
