DynamoIronPython2.7 package loaded but libraries missing

I have a couple users who are having issues running scripts that are using the IronPython2.7 engine in Revit 2023.

They installed the DynamoIronPython2.7 package, and it shows as loaded in Preferences>Package Manager>Installed Packages, and it shows up in the Python Engine Version dropdown on the python node,

but it is not listed in the Default Python Engine dropdown in Preferences>Features>Python.

Furthermore, going to the root folder of the DynamoIronPython2.7 package (C:\Users%USERNAME%\AppData\Roaming\Dynamo\Dynamo Revit\2.16\packages\DynamoIronPython2.7\bin) i find it missing the IronPython2.7 libraries.

Anyone have any idea what might be going on here?

Seeing same issue lately in 23/24. Commenting so I see the (hopeful) outcome…

don’t use the latest version of this package. It’s made for Dynamo 3.x/net8 only.
we updated the readme for IronPython3.x package, but neglected to do so for this package, sorry about that - we’ll update it.

Use v 2.5.
