Installing blender on linux doesn't respond?

I downloaded an older version of blender (2.76b). I Unpacked the archive, then I ran the Blender executable. I have Linux Mint. This message appears: > Unknown file type > >The file "blender" has no known programs associated with it. If you trust the source of this file, and have sufficient permissions, you can mark it executable and launch it. Or, you can use the Open With dialog to pick a program to associate it with. I click on **Make executable and run**. Then, nothing happens. It's as if didn't do anything. No error messages or anything! How can I solve this? **Edit** It's the first time to use Linux so here are the details. I write this in the terminal: > ./blender This is the response: > bash: ./blender: Permission denied
