Using Ironpython 3.4 and PythonNet3 engine in Revit 2025

[REDO10]

Hi all, @c.poupin
I’ve installed Revit 2025 which use Dynamo Core 3.3.0.6316 whithin only Cpython3 engine installed as you can see in the image below

How can install and use both engines Ironpyhton 3.4.2 and PythonNet3 ?

Thanks.

Hi @REDO10 you can install them from packagemanager

Hi @sovitek
Should I first upgrade to Dynamo Core 3.4 Release ?

Thanks.

[sovitek]

@sovitek
I can also install Dynamo Core 3.4 from packagemanager?

Thanks.

[sovitek]

dont think so, guess its shipped with the revit version, and if im not wrong 3.4 first come in 2026

I was able to download and use the IronPython3 engine, as you can see in the image below…However, I was unable to download the PythonNet3 engine (release 1.4.8). Does this mean that I need to have at least Dynamo 3.4 installed?

Thanks.

[sovitek]

not sure, but if i remember i use 1.1.1 in 25…but you could try some newer, and see if it will let you install

I also tried installing releases 1.4.5 and 1.4.7, but without success?

Thanks.

[sovitek]

try 1.1.1 maybe it works

1.1.1 should be compatible with 3.3 to 3.6.
Not sure about the 1.4 builds though.

[sovitek]

yeps right have just test it…havent tried 1.4.8 seems pretty new…i dont install, if what i try works…haha

[c.poupin]

PythonNet3 v1.4.x is intended for use with Dynamo 4.x (Net 10).

Use PythonNet3 v1.1.x with Dynamo 3.x (Net 8).

[REDO10]

I’ll try to install it later and see if it works

Thanks.
