NWAdmin.exe Unhandled Exception

[robert_sellers]

I am attempting to terminate workflows that are from 2013 that are still running. Read through the articles and posts then attempted:

• Workflows in Progress report. When I select the workflow to terminate, I get a blank page as a result.
• Trim the URL to the Instance ID provides the item but when I selecte terminate workflow, it states, "Ojbect does not exist."
• NWAdmin, i get the following output:
  • Unhandled Exception: System.IO.FileNotFoundException: Could not load file or ass
    embly 'Nintex.Workflow, Version=1.0.0.0, Culture=neutral, PublicKeyToken=913f6ba
    e0ca5ae12' or one of its dependencies. The system cannot find the file specified.
  • File name: 'Nintex.Workflow, Version=1.0.0.0, Culture=neutral, PublicKeyToken=91
    3f6bae0ca5ae12' at Nintex.Workflow.NWAdmin.Program.Main(String[] args)

Lazy approvals are not processing reliably and workflows are not being completed. need to get this system cleaned up. Thank you in advance to anyone that can assit me.

Hi,

Re-insatll Nintex in the farm as it looks like some files are missing.
Once installed make sure everything is activated properly.
