> Are you sure you downloaded the linux version?
Yes. Linux x86-32 - http://www.blender.org/download/get-blender/
> where did you extract the files to?
The file was downloaded and extracted into a NTFS partition called S. The actual path to the extracted folder - /media/S/Software/Design/Blender/blender .
> What command did you type in the terminal?
I opened the extracted folder in Thunar, right-clicked and selected 'Open Terminal Here'. I've assumed that a file called 'blender' is the executable that needs to be run. I've tried the following commands:
3. sudo ./blender
4. sudo blender
Then I tried to change the file permission:
1. sudo chmod a+x blender
2. sudo chmod 755 blender
However, the permission doesn't change at all. ls- l:
-rw------- 1 m m 62048708 May 9 23:31 blender
