Hello!
Trying to solve another issue, I uninstalled my most recent 32bit Psychopy (standalone version 2020.1.1.) today in order to install the 64-bit version.
But for some reason I cannot get it running.
I tried to install the 64-bit standalone version (and afterwards also the 32 one again), the installation succeeds, but when I start the application. Nothing happens. The cursor changes for a moment, but no window opens.
I followed the recommendations here, deleting the preference files, but it didn’t work
https://www.psychopy.org/troubleshooting.html#cleanprefs
when running form the command window, I get the following error:
C:\Users\admin>“C:\Program Files\PsychoPy3\python.exe” -m psychopy.app.psychop

(which translates into, the module was not found)
I also tried to install it through python, downloaded the most recent python version (3.8) and tried to install psychopy through the pip install command, but I get other error messages:

Does anyone have an idea what is going wrong? In the afternoon Psychopy was still running, but now it is not…
Thanks for your help,
