Good afternoon everyone. Does anyone have the procedure to correctly install the DynamoCoreRuntime2.19.0.zip package in Revit 2025? I’ve been looking for the link but can’t find it.
Dynamo for Revit can only be updated by updating Revit. If you need Dynamo 2.19 you need to utilize Revit 2024. Dynamo 3.0 to 3.3 are you only options for Revit 2025, and as 3.3 is tied to Revit 2025.4 which has some security patches in it… that is your option for 2025.
This is terrible news! This means that many tools that have been developed will not be usable in Revit 2025.
I’ve read that nodes developed with Python are having many compatibility issues. What alternative can you suggest for making the transition?
Your response will be very helpful. Thanks in advance.
Pretty nearly all Python code you developed for Revit 2024 will work with Revit 2025 if you used a supported build. Same with 2023, and most of 2022 there was guidance that it would be unsupported soon. If you used IronPython2 then you have been making a concious choice to use an unsupported tool for over 3 years now and with an added year of notice on top. So you have two options.
- Migrate to a new Python engine and update your code.
- Use the IronPython2 package to get the old Python engine on the system to buy you time during which you can migrate graphs from IronPython2 to a supported engine.
Note that the Python changes stemmed from security issues with IronPython2, as it hasn’t been supported since something like January of 2021.
Also note that option 2 will not be an option for ever - I would be surprised if it works in 2027 - so eventually you will run out of time to do a planned upgrade. As such focusing on getting into a supported Python engine needs to be a priority this year.
