Unable to install psychtoolbox (beginner)

Programming Help
1

I apologize if this is rude as my native language is not English.

I am trying to use Psychtoolbox for the first time and have installed it while looking at the Psychtoolbox website, but it is not working. I would like to know what I need to do.

environment
Windows11
MatLab R2024b

The work I have done

1.GStreamer
I downloaded the runtime installer for MSVC 64-bit (VS 2019, Release CRT) from the GStreamer website.
Under “Choose Setp Type” in Setup, I chose “Custom”.
In the “Custom Setup” section, I selected “Entire feature will be installed on local hard drive” from the button to the left of “GStreamer 1.0”.

2.Psychtoolbox
I downloaded the 3.0.19.16 zip file from GitHub.
I installed it by typing “SetupPsychtoolbox” in a command window with the “Psychtoolbox” folder in that file open on MatLab.

3.Test
I ran the “Totally Minimal Demo” script from the “Beginner Tutorial” that can be found on the Psychtoolbox (Scarfe Lab: Totally Minimal)
Then I got the following error.

WARNING: Couldn’t compute a reliable estimate of monitor refresh interval! Trouble with VBL syncing?!?

----- ! PTB - ERROR: SYNCHRONIZATION FAILURE ! -----

One or more internal checks (see Warnings above) indicate that synchronization
of Psychtoolbox to the vertical retrace (VBL) is not working on your setup.

This will seriously impair proper stimulus presentation and stimulus presentation timing!
Please read ‘help SyncTrouble’ for information about how to solve or work-around the problem.
You can force Psychtoolbox to continue, despite the severe problems, by adding the command
Screen(‘Preference’, ‘SkipSyncTests’, 1); at the top of your script, if you really know what you are doing.

次を使用中のエラー: Screen
See error message printed above.

[win, winRect] = Screen(‘OpenWindow’, screenid, clearcolor, winRect, pixelSize, numbuffers, stereomode, multiSample, imagingMode, specialFlags, clientRect, fbOverrideRect, vrrParams);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

By the way, I have rebooted MatLab and PC. If there is any other information you need, I will answer. I’m a beginner and don’t know anything, so anything you can tell me would be great.

Have a read of the error message you posted, as it explains how to get help on the error and also how to circumvent it (should you not be worried about accurate timing).

Thank you for your response

I’m sorry it took me so long to respond because of the lengthy help text and the time it took me to deal with it.
Thanks to you, I was able to move it at least! Thank you very much!
