Hi Andrea,
The Applications menu is not being loaded into MicroStation. I am not working in a workspace. I do not have Geopak or WaterCAD. I have confirmed launching InRoads (which results on the opening of MicroStation with the error 126 for InRoads unable to load library <DLL or MDL shared Library> CivUstAT). I had originally loaded InRoads prior to MicroStation (our in-house instructions were wrong), however, I then reinstalled InRoads after MS was loaded. I attempted to uninstall everything and "start from scratch" however I can not uninstall or repair InRoads so I installed the products in the above order.
