Where can I find the installed OpenStudio in my computer?

Hello,

I have downloaded and installed OpenStudio Release (Windows x64, v.3.7.0) from: https://openstudio.net/downloads

and OpenStudio Application (OpenStudio-3.6.1+bb9481519e-Windows.exe) from: https://github.com/NREL/OpenStudio/re...

Now I can see and launch the OpenStudio Application in my computer. However, I cannot find where the OpenStudio is. My questions are:

  1. Where can I find and open the OpenStudio? I have installed it under C:\ drive. When I opened the bin folder under C:\openstudio-3.7.0\bin, I could see openstudio.exe and install_utility.exe files, but when I double-clicked them, nothing happened and could not launch the OpenStudio.
  2. What are the differences between the OpenStudio and OpenStudio Application?

Please help.

Thank you in advance!

OpenStudio v3.7.0 is the latest SDK/CLI executable distributed by NREL. There's no GUI. One launches the CLI at the command line (e.g. PowerShell) - no point in double-clicking/launching the executable.

The OpenStudio Application is a frontend GUI program (distributed by the Coalition) interacting with the SDK/CLI backend behind the scenes, accessing most (though not all) of the SDK classes/methods. If you've installed the App v1.6.0, there's no point installing a separate instance of OpenStudio SDK/CLI v3.6.1; the latter is always packaged with the App (under /bin).

Working with the App v1.6.0 (SDK 3.6.1) and SDK 3.7.0 would be a one-way street: v3.7.0 can read/translate v3.6.1 files (not the other way round).

Thank you for your answer, Denis!

I understood, but would like to clarify one thing. When I went to the bin folder under the App (C:\openstudioapplication-1.6.0\bin), I see the following file:

openstudio.exe

However, when I double-clicked it, it was opened for a second and closed. Does this because I have installed a newer version of OpenStudio (= v.3.7.0)?

If so, is it better to uninstall OpenStudio v.3.7.0 and use the one under the App 1.6.0?

Please advise.

I'm writing this from a Mac, so the rest is from memory :].

You should be able to launch your App by double-clicking on "C:/OpenStudio-1.6.0/OpenStudioApp.exe" (or something along those lines). You can't launch its corresponding SDK/CLI (v3.6.1) by double-clicking on "C:/OpenStudio-1.6.0/bin/OpenStudio.exe" - it's CLI only. This is unrelated to its version number. A PC can hold multiple App/SDK/CLI suites, although interoperability would remain constrained (e.g. App v1.5.0 can't open v3.6.1 .osm files). And there is no App release (yet) supporting SDK/CLI v3.7.0.

So should you uninstall the SDK/CLI v3.7.0? You don't have to. Yet unless you need something specific from v3.7.0, there would be no point keeping it on your PC. If you plan to go back and forth between the App and a SDK/CLI (e.g. batch runs), then you can't mix and match SDK versions. The next release of the OpenStudio Application (v1.7.0?) will come with an updated SDK/CLI (e.g. v3.7.0, v3.7.1). Hope this helps.
