Windows (Vista and later) with PsychoPy 1.85 as library
Chronological instructions:
# (skip this step if you have Python 2.7 32 bit installed already and you want to keep it) Uninstall all versions of Python 2 that you installed previously. Use ''Programs and Features'' in the Control Panel. Also uninstall all Python packages that you see in ''Programs and Features''. Remove ''C:\Python27''.
# (skip this step if you have Python 2.7 32 bit installed already and you want to keep it) Install the newest 32 bit version of Python 2.7. You can download it [https://www.python.org/ftp/python/2.7.14/python-2.7.14.msi here]. If that does not work, go [https://www.python.org/downloads/release/python-2714/ here] and choose the 32 bit installer (Windows x86 MSI Installer). During installation choose 'add python.exe to path'. It is the last option in the list and may not be visible without scrolling down. # Logout and login again.
# Install [https://sourceforge.net/projects/wxpython/files/wxPython/2.8.12.1/wxPython2.8-win32-unicode-2.8.12.1-py27.exe/download wxwidgets 2.8] If that does not work, go [https://sourceforge.net/projects/wxpython/files/wxPython/2.8.12.1/ here] and choose wxPython2.8-win64-unicode-2.8.12.1-py27.exe. It is the ancient library used by PsychoPy for its IDE. It is essential that you do NOT install wxpython/wxwidgets from another source.
# Download this [https://www.socsci.ru.nl/wilberth/nocms/python/DEPS1853.txt file] (right-click -&gt; save link as...) with all other requirements. Use Windows file Explorer to go to the folder where you downloaded it. Shift-right-click to the right of the files (make sure the window is wide enough). Choose 'Open command window here'. From a command line type: <br /><tt>C:\Python27\Scripts\pip install -r DEPS1853.txt</tt><br /> Enjoy watching, and see if there are any errors.
# Now Psychopy is installed on your system. You may want to make a link that opens ''C:\Python27\Lib\site-packages\psychopy\app\psychopyApp.py'' with ''C:\Python27\pythonw.exe'' and has ''C:\Python27\Lib\site-packages\psychopy\app\Resources\psychopy.ico'' as icon.
