Blender is not running after download, how to make it run?

I just downloaded the latest Blender version and it is not running when I double-click it or run it through the terminal. I'm the only person using the machine as currently the administrator in the distro. The only way to run the application is to call it as super user and even when I get it to open I cannot install certain purchased plugins due to the current permission configured Blender. That is also true to some other apps that I had working in Linux and after updating the kernel last week it seems that the permissions got changed. I'm somewhat new to Linux and don't want to mess with the permissions myself using chmod or chown as I learned it the hard way and had to re-install Linux. That said, how can I permanently run Blender without having to do so as super user?
