Application updates¶
Application Updates publishes release metadata that supported TEKControl applications use to determine whether an installer is available. It does not upload or host the installer itself; each release points to an MSI URL.
Open General Administration, locate General System Administration Settings, and select Application Updates. This screen requires platform-administrator authority.
Danger
Enabling an incorrect global or mandatory release can affect every matching device the next time it checks for updates. Validate the package and use a targeted pilot before broad rollout.
Review the release inventory¶
The grid shows:
| Column | Meaning |
|---|---|
| Application | Application code supplied by the updating client. |
| Channel | Release stream such as stable, beta, pilot, or a custom channel. |
| Version | Version advertised to the client. |
| Type | Mandatory or Optional manifest result. |
| Status | Enabled or Disabled. Disabled releases are not returned to clients. |
| Published UTC | Activation timestamp stored for release selection. |
| Scope | Global, one target, or the number of SITE and DEVICE targets. |
| MSI URL | Installer location returned to an eligible client. |
Inventory rows are grouped by application and channel and then ordered by newest publication time. Search matches application code, channel, version, MSI URL, and release notes. It does not search target values.
Use Refresh after another administrator or deployment process changes a release.
Available actions¶
- Add Update creates a disabled, mandatory stable-channel draft published at the current time.
- Edit changes release metadata and replaces its target list when saved.
- Delete permanently deletes the release and all of its targets after confirmation.
Prefer disabling a release before deletion. Disabled records retain the rollout definition for investigation and possible rollback. Deletion has no restore action in this screen.
What a client receives¶
A client submits its application code, channel, current version, site ID, and device identifier when available. TEKControl returns the newest eligible release by publication time and record ID. The manifest includes version, MSI URL, optional SHA-256, mandatory flag, minimum current version, and release notes.
An enabled row in the grid is not sufficient by itself. Publication and expiration windows, target matching, current-version comparison, and minimum-version eligibility all affect the response. See Targeting and release selection.
Operational boundary¶
The portal publishes update metadata. The installed application is responsible for checking, downloading, validating, presenting or enforcing mandatory behavior, launching the MSI, handling elevation, and reporting its new version. A correct manifest does not guarantee download, installation, restart, or healthy operation.
Use Rollout and rollback for a safe release sequence and Troubleshooting when clients do not receive or install an expected update.
