I am creating a custom action through Visual Studio. I added a reference to Spire.Pdf. I deployed the custom action and added the custom action to my workflow, however I am receiving the following error.

Error in Basic Action. Could not load file or assembly 'Spire.Pdf, Version=3.9.462.2040, Culture=neutral, PublicKeyToken=663f351905198cb3' or one of its dependencies. The system cannot find the file specified.Error

Check if your Spire assembly is registered on GAC on all your SharePoint servers.


Hi,

Make sure your Spire.PDF dll is included in your wsp.
