Dynamo Toolbox Doesn't load

Hi, I can’t seem to get dynamo toolbox to show up for the life of me. I’m currently running the following.

  • Windows 10
  • Revit 2018.3
  • Dynamo 2.0 +
  • Ironpython 2.7.3
  • .NET 4.0.30319.42000

Things I’ve tried:

  • Uninstalling + Reinstalling Dynamo
  • Disabling Revit Add-Ins (To see if there is a conflict)

All of these things to no avail. Does anyone know what the issue might be?

@chrisishere see this post: Dynamo 2.0 - Library Missing I believe it is the same problem

Ok so:

  • I’m running Revit 2018.3
  • I removed PNIidModeler from C:\Program Files\Autodesk\Revit 2018\AddIns

Still not working. Let me know if there is other possible reasons.

@chrisishere please open the dynamo console from the view menu and look for errors:

also you can try installing this dependency:
https://www.microsoft.com/en-us/download/details.aspx?id=40784

It’s possible it is missing from your machine (you can check in window features)
related:

I recall this could be an add-in as well. Disable them all and see what comes up (or doesn’t).

Tried installing Visual C++ redistributable. It was already installed, so I uninstalled/reinstalled. Still no luck.

Ok opening up the console I’m seeing this possible error:

LibraryUI: The invocation of the constructor on type 'CefSharp.Wpf.ChromiumWebBrowser' that matches the specified binding constraints threw an exception.

what version of the visual c++ redistributable do you have installed?

Apparently, I have quite a few:

hmm, can you verify you have .net runtime 4.5.2 installed?

usually the error you are seeing indicates this problem:

but it could be some other dependency…

Also, can you please remove all dynamo packages (also note your extra package paths etc) to start with a clean env so we can rule out other packages which might reference other versions of CEF.

I have confirmed that 4.5.2 is installed and also I have no packages installed.
