Hello, I installed the Dnn 9.1.1 upgrade over our existing Dnn 7.4.2 installation but I am now getting an error loading the Dnn.EditBar.UI.

I took the upgrade zip file and followed the instructions - first copying into the DotNetNuke directory and then following the Wizard.

Since then I have had to update some of my libraries to later versions (i.e. system.web.http) but now I am getting an error loading Dnn.Editbar.UI.

Do I need to download this separately?

Thanks
