I am running Revit MEP 2008 off of a network deployment. When I try to do heating and cooling calcs, the VE interface appears but when I click Calculate, the Apache Thermal Analysis progress bar just sits there and nothing happens. When I click the <Virtual Environment> button and select a new project I get the error message in the attached image.
When I go to "Add/Remove Programs", Revit MEP 2008 - IES VE Loads Calculations is listed (900Mb).
