Error on solution packager

Jan 16, 2014 at 9:43 AM
Hi, I'm trying to use this utility in my solution (unmanaged solution) and I added all components from CRM2011WorkflowUtilities solution to my solution by add existing.. End everything works fine. I also use SolutionPackager to fragmentation solution. I can unpack solution but when I'm trying pack it again i receive error:
"Following root components are not defined in customizations:
Type='PluginAssembly', Id (or schema name)='PluginAssembly-CRM2011WorkflowUtilities, Version=, Culture=neutral, PublicKeyToken=56e578f179199f26'."

I've checked that in customization xml file field with this component is empty (no fields like fileName etc). I have no idea what could be cause of this issue.
