AutoPLANT Modeler - Unable to open dcl file


we have installed Autocad 2014. and AutoPLANT Modeler version

Before AutoPLANT Modeler version we want to try AutoPLANT Modeler version, but this version requires for Autocad 2015.
Version was uninstalled and now we want run version

After installation we want run Piping in but they give this error:

AutoPLANT Loaded...

Unable to open dcl file aptmp\1\eda.dcl
Unable to initialize dialog eda, in dcl file aptmp\1\eda.dcl

Can somebody explain this error because Piping don't work?

Thanks for help and best regards
