We recently installed PowerInRoads V8i (select series 4) and cannot use any of the inroads commands such as Inroads, inroads survey, inroads Bridge, etc...
I get this error every time: MDL Loader: Could not load application c:\program files (x86)\bentley\inroads group V8.11\bin\civustAT.ma
I have tried repairing the installation but had no luck. This is a clean install on a machine without any other versions of Microstation.
From my understanding, the ability of "post loading" InRoads products once SS3 was released was going away. This was announced at the Bentley conference in 2013.
You specifically need to start from a Windows shortcut the InRoads product of your choice. This would be the same for SS4 I would imagine.
