But more specifically when you try the following?
The application doesn’t start
You may find that you try to launch the PsychoPy application, the splash screen appears and then goes away and nothing more happens. What this means is that an error has occurred during startup itself.
Commonly, the problem is that a preferences file is somehow corrupt. To fix that see Cleaning preferences and app data, below.
If resetting the preferences files doesn’t help then we need to get to an error message in order to work out why the application isn’t starting. The way to get that message depends on the platform (see below).
Windows users (starting from the Command Prompt):
Did you get an error message that “This application failed to start because the application configuration is incorrect. Reinstalling the application may fix the problem”? If so that indicates you need to update your .NET installation to SP1 .
open a Command Prompt (terminal):
go to the Windows Start menu
select Run… and type in cmd
paste the following into that window (Ctrl-V doesn’t work in Cmd.exe but you can right-click and select Paste):
“C:\Program Files\PsychoPy2\python.exe” -m psychopy.app.psychopyApp
- when you hit you will hopefully get a moderately useful error message that you can Contribute to the Forum (mailing list)
