When I edit a Task Sequence and click on some Task Sequence steps I get an “Error” dialog box which states:
Could not load file or assembly 'file:///C:\Program Files (x86)\Microsoft Configuration Manager
Console\AdminUI\bin\Microsoft.BDD.SCCMActions.dll' or one of its dependencies. The system cannot find the file specified.
I click “OK” but the Task Sequence closes.
Make sure the MDT Deployment Workbench is installed and integrated on the same machine as the ConfigMgr Admin Console. In this case only the ConfigMgr Administrator Console had been installed on the local machine and not MDT as well.
Copying the “Microsoft.BDD.SCCMActions.dll” from this location on the Site Server:
\\<server_name>\<share>\Program Files (x86)\<installation_directory<\AdminUI\bin
to the same location mentioned in the error i.e.
C:\Program Files (x86)\Microsoft Configuration Manager Console\AdminUI\bin
is not sufficient to resolve this error. You need to install the Deployment Workbench and then run “Configure ConfigMgr Integration” to resolve this issue.
