USB key version of Blender ?

Hello !

I'd like to train myself at blender when I have free time at school, but sadly the computers doesn't allow you to install anything on them. (That make sense ikr)
But I can't find any usb key version of blender on the internet.
Do you know how could I use blender ?

 

Ah ! Thanks you a lot !

 

Cant you just download the portable version of blender from their website? I havent run it on usb, but as far as i know, it doesnt require anything to run besides itself.

 

Do not know, I've never tried.

 

I use the portable version and I can confirm it works from a USB pen-drive.
