Some time ago I thought it was a wise idea to install Workflow Manager for SharePoint 2013. Unfortunately, it's become more of a headache than a help. Long story short, at one point I stood up a Workflow Manager server which is now "removed". I followed this article:

https://sharepointinaction.wordpress.com/2014/01/27/uninstallingremoving-sharepoint-2013-workflow-manager-farm/

Only thing though, I didn't even have the workflow manager installed on ANY related server. I went through and did the rest of the removal process. The problem now is I'm still getting errors when I try and launch "Workflows" from a list item. This time it says "File not found".

And looking in ULS I see this:

System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Workflow.Client, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified. File name: 'Microsoft.Workflow.Client, Version=1.0.0.0, Culture=neutral

I've run SharePoint Products and Config Wizard and restarted IIS. How do I make it point back to the OOB version of Workflows?

Any and all help would be appreciated!

It is two step process

  1. Run the WF wizard and leave the farm, uninstall WFM from servers and other related componenets. Also delete the related databases.
  2. Now remove / Uninstall WFM Client from all SharePoint servers, remove the Workflow Services Application from Central admin ( CA -> Application Management -> Manage Services Application -> on this page click on WF service application and click delete from ribbon).

    Thanks Waqas, that was it! Removed the Workflow Service Application Proxy and worked right off the bat.

I have seen you have already solved, hoever, for completeness, if you want to do a full clean-up, follow these steps:

1)Leave WFM/SB Farm 2) Uninstall updates and application in the following order and one at a time:

  • Service Bus CU1
  • Workflow Manager CU1
  • Service Bus 1.0
  • Workflow Manager 1.0
  • Workflow Manager Client 1.0
  • Microsoft Windows Fabric
  1. Log into SQL server and delete Service Bus and Workflow Manager databases.
  • SBManagementDB
  • SBGatewayDB
  • SBMessageContainer01
  • WFManagementDB
  • WFInstanceManagementDB
  • WFResourceManagementDB
  1. Delete the folder “Workflow Manager” under C:\Program Files\Workflow Manager (this is required only if you want to reinstall Workflow Manger later on)

Hope this help some others
