Dynamo tab disappears after installing Revit 2020.2.2 Hotfix Update

by Dennis Collin

Recently a hotfix for Revit 2020.2 was released that addresses several stability and performance issues relating to MEP fabrication parts, GBXML export, FBX and linked topography. The update can be installed either from Autodesk’s Desktop App or via your Autodesk account.

After installing the update some users have found that their Dynamo tab disappears. To restore the tab, replace DynamoRevitDS.sig and DynamoRevitVersionSelector.sig files to the following location:

C:\Program Files\Autodesk\Revit 2020\Addins\DynamoForRevit\Revit\

The replacement files can be downloaded from here:
