    Solution
    1. Retract all Nintex Workflow solutions wait for each one to retract using your Central Administration, in this order:
      • nintexworkflow2013backwardscompatibilityui.wsp
      • nintexworkflow2013enterprisefeaturesbackwardscompat.wsp
      • nintexworkflow2013enterprisefeatures.wsp (First retract from all web apps, then from Central Admin)
      • nintexworfklow2013.wsp (First retract from all web apps, then from Central Admin)
      • nintexworkflow2013core.wsp
    2. Remove all retracted Nintex Workflow Solutions.
    3. Delete all Nintex Workflow assemblies from GAC_MSIL: C:\Windows\Microsoft.NET\assembly\GAC_MSIL
      • Nintex.Workflow
      • Nintex.Workflow.AdministrationPages
