Title

Beacon upgrade/install of 2021 R1.4 (17.4.1) or later may fail if .NET 4.7.2 or later is not installed

Symptoms

The beacon installer for 2021 R1.4 (17.4.1) and later requires that .NET 4.7.2 or later be installed on the system. If this version of .NET is not present on the system the launch condition will fail and the install will abort. If the beacon is upgrading, it will continually try to start the upgrade until addressed.

Diagnosis

The new version of the beacon requires .NET 4.7.2 or later and if this is not installed the install will abort. When the upgrade aborts, the beacon will constantly try to upgrade and show a message that an upgrade is in progress when you launch the UI.

You can find more details in the FlexNet Beacon.msi.log file found in the Temp folder of the account used to perform the upgrade (which is commonly the account used to run the FlexNet Beacon Engine service). This file will include a message like the following:

Action start 9:26:22: LaunchConditions.
MSI (c) (78:74) [09:26:47:925]: Product: FlexNet Beacon -- Microsoft .NET Framework 4.7.2 Full package or greater needs to be installed for this installation to continue.
Action ended 9:26:47: LaunchConditions. Return value 3.

Solution

If upgrading, please perform the following steps

Stop the FlexNet Beacon Engine Service
Install .NET 4.7.2 (https://support.microsoft.com/en-us/topic/microsoft-net-framework-4-7-2-offline-installer-for-windows-05a72734-2127-a15d-50cf-daf56d5faec2) or 4.8 (https://support.microsoft.com/en-us/topic/microsoft-net-framework-4-8-offline-installer-for-windows-9d23f658-3b97-68ab-d013-aa3c3e7495e0)
Restart the FlexNet Beacon Engine Service to have the beacon try the upgrade again

If this is a first-time install, you only need to install .NET 4.7.2 or 4.8 and then run the upgrade again.
