CHMI Automatic Software Upgrade

Function presentation

The CHMI application has a build-in facility to automatically download and install the CFMU software upgrades when needed.
This upgrade facility will identify the CHMI version currently installed on your PC and will check automatically if any CHMI software upgrade is available.
The CHMI Software Upgrade process involves the following phases:

Check phase: automatic verification if a new software upgrade is available and ready for download.
Download phase: initiated when new software upgrade is identified and available for download.
Install phase: proposed when newly downloaded software upgrade is ready for installation.
Problem reporting during the different software upgrade phases.

Check phase

The upgrade facility is designed to check for software updates when the CHMI application is started.
If the check phase is interrupted, it will resume automatically at a later time or on user request.
If required, or if notified by the CFMU Technical Support, the user may start the check phase himself for the availability of software upgrades.
An animated icon is displayed at the bottom right of the CHMI framework (not the Windows Task Bar) while processing this check.

A mouse click on this animated icon will display a contextual action menu.

Selecting the Show menu option will display the CHMI Software Upgrade dialog.

If there are no software updates available, the Software Upgrade facility resets. It will automatically check again in 24 hours if the application is not stopped earlier.
In this case, the Download checked icon is displayed at the bottom right of the CHMI framework.

When the check is initiated manually from the menu and there is no new CHMI software available, a message box will inform the user before the Software Upgrade facility resets.
