Revit Python Shell setting default to IronPython 2.7

[roycasumpang]

Hi All,

For some reason my Revit Python Shell default changed to IronPython 3.4 instead of IronPython 2.7, and when I import pyrevit form libraries it display this error. It used to run in IronPython 2.7 and never had a problem. Is there a way to change the default IronPython version for RPS to use?

Thanks!

Hi!

IronPython 3.4 was implemented in the latest (2.0.0) release of Revit Python Shell (RPS). 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 here.
