Radiator v4.22: Now with Windows installer package!

In our efforts to make Radiator easier to install, deploy and update in Windows environment, we have build a Windows installer package for Windows installations. The new package comes as an MSI that can be installed silently when needed. Supported Windows versions are Windows Server 2012 or newer, but older Windows Server versions can also be used provided they have at least PowerShell 3.0 installed.

These new packages are now first available at:

The MSI package includes Strawberry Perl for convenience, so that separate installation of Perl is no longer needed. However, if your environment already has a Perl installation, Strawberry Perl in Radiator MSI package does not disturb it. Since Radiator does require certain Perl modules that are available in the Windows package, it is mandatory to use the Radiator binaries from provided command line shortcuts. These shortcuts are located under Program Files\Radiator folder and for convenience shortcut to this folder and to reference manual are also available in the Start Menu under Radiator Software.

In addition of the Strawberry Perl command line shortcuts there are other important files available on the Program Files\Radiator folder. For example the basic configuration that is automatically installed and installation time log. This folder is never cleaned during upgrade or uninstallation, so this is the suggested location for all your own configurations.

 Differences between the new Windows package and installation from zip 

  • Radiator will install itself automatically under Radiator\Radiator in the drive with largest space available
  • Automatically provided dictionary and users are no longer copied to Program Files\Radiator, instead they should be used from original location. If the files are changed locally, then these should be stored under Program Files\Radiator so they are not removed
  • Installation and other logs are available under Program Files\Radiator
  • Basic configuration file is available under Program Files\Radiator
    • Basic configuration file name has changed to radiator.conf
  • Strawberry Perl is included in the Windows package
    • Only way to avoid this is to install manually from package as before
    • Strawberry Perl is not in path, so when running commands manually they must be done from Perl command line shortcuts available under Program Files\Radiator
  • Windows Service with basic configuration is created automatically
    • This helps testing that installation has been successful with radpwtst
  • Radiator Software is added to Start menu, with shortcut to Program Files\Radiator and link to reference manual
  • Binary files are not copied under Strawberry Perl, instead they are available in Radiator location



Installing, upgrading and uninstalling the Windows Package


Installing the new Windows package is simple. Once the MSI file is copied to the target machine, double click the file, approve license screens, and the installation is done. It is not possible to select where Radiator is installing, it will automatically install to the drive with most space available under Radiator\Radiator. Strawberry Perl is installed under Radiator\StrawberryPerl-Radiator and configuration and logs will go under Program Files\Radiator.

Upgrading works similar way, double clicking the MSI file on the target machine will launch the upgrade functionality. Upgrade will not remove anything from Program Files\Radiator, and also the Windows Service will be available as it was before the upgrade.

Uninstalling can be done either from double clicking the MSI file used to install the software or from Control Panel - Add/Remove Programs. When uninstalling via MSI file, the only option available is Remove. Repair or Change is not available. All Radiator Software specific items are cleared out during the uninstall, except the Program Files\Radiator folder. This is to ensure your configurations are not lost.

The MSI also supports silent operations, so it is possible to start the installation, upgrade, or uninstallation from command line without any UIs.

Note that the MSI package is not signed.

How to change the Windows Service configuration


When Radiator Software is installed with the help of MSI package, it has automatically created Windows service with basic configuration. This configuration is mainly aimed to help testing with radpwtst that the installation was successful. Changing the configuration to the Windows Service requires manual steps:

Create the configuration and store it under Program Files\Radiator

Open Windows Services

Stop the Radiator service and close the Services dialog

Open Perl command line Elevated from Program Files\Radiator by double clicking

Initialize the new configuration to Windows Service with command:
perl  "C:\Radiator\Radiator\radiusd" -installservice -config "C:\Program Files\Radiator\lsa_eap_peap.cfg" -prepend_env PATH:C:\Radiator\StrawberryPerl-Radiator\perl\site\bin;C:\Radiator\StrawberryPerl-Radiator\perl\bin;C:\Radiator\StrawberryPerl-Radiator\c\bin;

Open Windows Services and verify from the Radiator service properties that the new configuration is available. Start the service.

Opening ports in Windows firewall for Radiator


For connections to work from outside localhost, UDP ports 1645, 1646, 1812, and 1813 need to be opened from the Windows firewall.

Open the Windows Defender Firewall with Advanced Security

Create new Inbound Rule

Rule Type should be Port

Select UDP protocol and specify the needed ports: 1645, 1646, 1812, 1813

Allow the connection

Apply the rule to all profiles

Give suitable name for the rule and Finish the creation

New firewall rule is now active, and incoming Radiator connections are possible.
