I am getting the following error when trying to deploy the solution NINTEXWORKFLOW2016CORE.WSP in SharePoint 2016.
Error: The copying of this file failed: Bin\NintexWorkflowStart\Autofac.dll.
The process cannot access the file 'C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\Bin\NintexWorkflowStart\Autofac.dll' because it is being used by another process.
I have 2 App servers and 2 WFEs. The error is only on the server that houses central admin. It deployes to the other three servers successfully.
