It used to run in IronPython 2.7 and never had a problem.

If you want to use IronPython 2.7 I think you need to unistall you current RPS version. And download the previous release (1.0.2). You can find it <A href="https://github.com/architecture-building-systems/revitpythonshell/releases" target="_blank" rel="noopener">here</A>.</P> Sun, 26 Feb 2023 10:55:55 GMT https://forums.autodesk.com/t5/revit-api-forum/revit-python-shell-setting-default-to-ironpython-2-7/m-p/11782076#M13689 architect.bim 2023-02-26T10:55:55Z Re: Revit Python Shell setting default to IronPython 2.7 https://forums.autodesk.com/t5/revit-api-forum/revit-python-shell-setting-default-to-ironpython-2-7/m-p/11799253#M13690 <P>Yes, this one works.
