When attempting to run the DocumentTool.exe to perform a migration or restore job, the following error is shown; 

"Unhandled exception: System.IO.FileNotFoundException: Could not load file or assembly 'DocuWare.Generic, Version=, Culter=neutral, PublicKeyToken=[]' or one of its dependencies. The system cannot find the file specified." 

This behavior can be fixed by performing the following steps. 
  1. Browse out to C:\Program Files (x86)\DocuWare\Setup Components,  find and copy the "DocuWare.Generic.dll" file, then paste it to C:\Program Files\DocuWare\Background Process Service

  2. Next, open the "DocumentTool.exe.config" located in C:\Program Files\DocuWare\Background Process Service, go to line 74 or search for the value publicKeyToken="b03f5f711d50a3a.

  3. We'll want to now change the newVersion value from to so that it looks like the following, 

        <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
            <assemblyIdentity name="System.Runtime.CompilerServices.Unsafe" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
            <bindingRedirect oldVersion="" newVersion="" />

  4. Save the changes, then rerun the DocumentTool.exe, which should proceed without an error.
