Hello Team,

We are using Flexera One and recently upgraded our FlexNet Beacon from version 22.4 to 25.1.0. Following the upgrade, the Beacon UI is not opening successfully and displays the following error message:

"Beacon service not found."

"The application could not start because it could not connect to the FlexNet Inventory Beacon Engine service. Please check that the service is running."

However, when we check Windows Services, we can see that the FlexNet Inventory Beacon Engine service is present and running successfully, which makes this behavior somewhat confusing.

As part of our troubleshooting, we reviewed the prerequisites for Beacon version 25.1.0, which indicate that .NET Framework 4.8 is required.

We verified the installed .NET Framework version using the following PowerShell command:

(Get-ItemProperty 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full').Version

The output shows 4.8, suggesting that .NET Framework 4.8 is installed on the server.

However, when checking Add or Remove Programs, we can only see .NET Framework 4.6, and there is no visible entry for .NET Framework 4.8. To further validate this, we attempted a manual installation of .NET Framework 4.8, but the installation failed with the following error:

"Installation did not succeed. .NET Framework 4.8 has not been installed because: Cannot find object or property."

For reference, I have attached the following:

1. Beacon UI error message
2. Beacon Engine log screenshot
3. .NET Framework installation error screenshot

Has anyone encountered a similar issue after upgrading from Beacon 22.4 to 25.1.0? Any guidance, recommendations, or troubleshooting suggestions would be greatly appreciated.

Thank you in advance for your assistance.

Regards,
