PsychoPy (latest version, W10 refuses to launch)

Win10 - was on previous version [2021.1.2]… coding away happily. it crashes when syncing with gitlab. Relaunched… splash appears then disappears without GUI or processes. Install latest version [2021.1.4] assuming i have hosed something. It fails to launch.

“C:\Program Files\PsychoPy3\python.exe” -m

Results in

C:\Users\artaxerxes>“C:\Program Files\PsychoPy3\python.exe” -m
pygame 1.9.6
Hello from the pygame community.
WARNING:matplotlib.font_manager:findfont: Font family [’’] not found. Falling back to DejaVu Sans.

This command makes it launch… and everything appears to work…from the PsychoPy instanced from CMD window. If i close this instance it still fails to launch from the standard PyschoPy3 shortcut.

This… resolved itself? A few reboots later. Leaving it here so others may marvel.

No - the issue has returned. Fails to launch from the shortcut… lanuches freely from CMD - “C:\Program Files\PsychoPy3\python.exe” -m

Continuing the discussion from PsychoPy (latest version, W10 refuses to launch):
Hi. I have met the same problem. Have you solved it and how?

Press Windows + R

type cmd in the Run box that appears.

in the terminal window copy and paste this command;

“C:\Program Files\PsychoPy3\python.exe” -m

…this will either work, or tell you the other reasons it isn’t working!

Many thanks for the prompt reply! It works!
