# Platform-specific instructions: Windows

## Dependencies

If you are using Windows, download the following installers and follow their instructions:

- Python 2
- Pygame
- PyOpenGL

and, if needed:

- PySerial
- PyParallel and giveio
- NumPy

## Installing Expyriment

To install the latest version of Expyriment, download “expyriment-0.7.0-win32.exe” from the Release page and execute it.

## Notes

Do not start your experiments out of IDLE

> If you are using the IDLE editor that comes with the Python installation, be aware that IDLE itself is written in Python. Starting your Expyriment programme out of IDLE (by clicking on “Run” or by pressing F5), might thus lead to improper timing!

> We therefore strongly suggest to run Expyriment programmes from the command line when testing participants.
