I know this old but only first post, a simple question and no answer. How did we miss this?
I do not install Blender. Do you know you can use it out of the box? In the downloaded folder there is a application file with the Blender icon just send a shortcut to the desktop.
What operating system do you use?
Can you show us the error message? ( copy paste )
