# Run the Spotfire Enterprise Runtime for R Console

Regardless from where you use an installation of Spotfire® Enterprise Runtime for R ( a/k/a TERR™) , you can run a console interface for writing and testing functions scripts, or for running a batch process.

- If you have installed the stand-alone TERR™ console, for example, on Microsoft Windows, you can run the TERR console by double-clicking the program from the Start menu in Windows.
- You can run the engine’s executable TERR.exe from its installation location. For example, on Windows, the engine is installed in C:\Program Files\spotfire\terr61\bin.
- If you are running TERR in Spotfire, you can launch the TERR engine from the Spotfire menu by clicking Tools > TERR Tools, and then clicking Launch TERR Console. Also, you can find the executable in the same TERR Tools dialog by clicking Copy TERR engine Path to Clipboard.
- If you prefer to work in an integrated development environment, you can use the TERR engine with RStudio®. See Configure RStudio to use Spotfire Enterprise Runtime for R.

You can customize your TERR session by using the files TERRenviron, TERRprofile, .TERRData, and `.First`. See Customize the TERR environment at startup for more information.
