Cannot Select IronPython2 in Dynamo for Revit 2024 Despite Installing Package

I am currently using Revit 2024.3 and the Dynamo version shown in the image.

I would like to use IronPython 2 to create a Python script, but I am unable to select IronPython 2 even though I have installed the DynamoIronPython2.7 (version 3.2.1) package.

If you know how to resolve this issue, I would greatly appreciate your advice.

Thank you very much.

Dynamo Revit 2024 is included PythonNet 2.5
So you can run Library based .Net without install IronPython

You will need to uninstall DynamoIronPython2.7 release 3.2.1 and install version 2.5 which is the last version that works with Dynamo 2
