Does anyone know why this is popping up when i hit run in dynamo player


It could be because you have multiple versions of dynamo installed and the player does not know which one to use. Opening Dynamo and selecting a version could fix it, or if it is bugged, you would have to uninstall all other versions you are not using.

That usually happens when you try to open a 2.0 version graph (json) into dynamo 1.x (xml)
