Dynamo problem: nodes are not visible, dynamo is very slow and functions are frozen



a colleague has a problem with dynamo.
He has Revit 2017 and Dynamo 1.3.

  1. the nodes of Dynamo scripts are not visible (OOTB-nodes)
  2. interaction with Dynamo is very slow, for example the start from Revit
  3. if a script is open, you can’t select a function or anything else

    We deleted all packages and Dynamo 1.3 and reinstalled Dynamo 1.3 (last version), but the problems are the same.
    What can i try to solve this problem?

EDIT: In Revit it isen’t possible to choose between Version 1.2 or 1.3 (maybe this is important)


Is 0.9 installed on your system? if not needed anymore, do uninstall 0.9


No, 0.9 is not installed, but 1.2. Do i need to delete 1.2?


Nah, I’ve had many issues with 0.9 AND 1.3 installed. After I uninstalled 0.9 all my problems were gone.
I have 1.2 and 1.3 both installed ( I can’t even uninstall 1.2 I believe) fyi.


Looks like it was a bad update, but try checking the graphics card first. Need to force dynamo to always use the high end card not a mix.

If that doesn’t work uninstall all things dynamo, run microsoft’s FixIt utility to ensure the registry is good and install only 1.3.2.


The autodesk support says, thats a bigger problem (they didn’t describe it)…
The developer can’t handle it now, but they working on it…
They said, only a completely cleaned and reinstalled pc/software would be a solution…


Yes: uninstall all things dynamo, run FixIt utility to ensure all things dynamo are gone, and install a clean version of 1.3.

This is the clean version my colleague mentioned.


I did already everything you mention (more than once). And they did it too. Nothing helped.
They want a fresh new pc…so new Windows installation.


Ok. Did they collect any system information so we can recreate?


diden’t know…but they closed the support case


I’ll pm you.


Jacab gave me the tip to start a script with Dynamosandbox.
Everything worked fine there. So i checked some add-ins.

The Add-in GeberitPluviaRevit has caused the problem.

Thanks for help
