The list of workflow actions on the server references an assembly that does not exist. Some actions will not be available in SharePoint Designer

When I tried to create a SharePoint 2010 workflows via SharePoint Designer 2013, I got the following error

The list of workflow actions on the server references an assembly that does not exist. Some actions will not be available.

Cause:

  • This error may occur if the system does not have enough memory,
  • In some cases,This error comes up if the current account don’t have local privileges,
  • Cache issue,
  • WSS.Actions file contains a reference to a custom action.

Solution:

  • This error may occur if the system does not have enough memory,
    • If you work on VM,you will need to check its memory allocation.
      • if memory was less than 6 GB you will need to increase it.
  • If the current account don’t have local privileges, you will need to add it to local administrator group.

Local users and group - Computer management

  • If the problem still persists, you will need to clear the cache of the following folders
    • %USERPROFILE%\AppData\Local\Microsoft\WebsiteCache
    • %USERPROFILE%\AppData\Roaming\Microsoft\SharePoint Designer\ProxyAssemblyCache
    • %USERPROFILE%\AppData\Roaming\Microsoft\Web Server Extensions\Cache
  • If the problem still persists,try to delete the previous folders.
  • If the problem still exists that mean the Workflow actions has been extended with a custom action developed in Visual Studio.
    • These custom actions are loaded when your workstation reads the WSS.ACTIONS file on the server.
    • The file is located in the 14 hive under Template\1033\workflow.
    • WSS.Actions file contains a reference to a custom action .dll.
    • Take a WSS.Actions file backup then remove it.
