Hi experts,

I am encountering the problem of opening MRIcroGL. There was an error message saying that unable to load OpenGL 2.1. 

Not sure if it was because my laptop went on blue screen and shutdown itself once. Hence, the application has been crashed thereafter. It never was a problem though...

Would somebody help with this issue? Thank you so much in advance!

I'm using Window 11 to run the application. 

Faithfully,
Krystal

I think the easiest solution might be to start MRIcroGL from the command line with the -R option to reset everything. Alternatively, you could see if there are any files named 'MRIcroGL.ini' on your computer and remove them.

You make it sound like MRIcroGL used to run on this computer, so you should check the graphics drivers are up to date.

I do think for Windows you need a "x64-based PC," not a "ARM-based PC". You can check this by running the following in your command line:
  systeminfo | findstr /C:"System Type"


Finally, you could see if other OpenGL programs work on your computer. I have not tried this, but a program like this might give you some insight:
