Feels like I've been running in circles but how do I found that out? What lead me to cause was trying to install a plugin from IOTAP but the import failed.
'PluginType' entity doesn't contain attribute with Name = 'customworkflowactivityinfo'.
Any way of checking the latest rollup for CRM. I'm using 2011 that was an upgrade from 4 and it's online.
You can find an overview of Dynamics CRM version numbers on MSDN blog Dynamics CRM in the Field.
B.t.w. rollup 14 should fix your problem.
