noobie user - Energy plus is v9.0.1 and seems to runin standalone mode fine - as I have run the excercise files successfuly. installed openstudio v2.8 on Win7pro64 - the file builder and interface with Sketchup works ok and I have built a file with most of my desired input data complete, but when I hit run, the following output files are generated.

I don't see either openstudio or energy plus in my root drive path statement, but I don't know if they should be. I am running the files in the main Open Studio directory, which is installed on the C drive, as is the energy plus folder.

OpenStudio v2.8.0 requires EnergyPlus version 9.1.0, not 9.0.1 according to the OpenStudio Version Compatibility Matrix.

Reinstall OpenStudio and make sure you check the box to install EnergyPlus as well.
