Installation Error

I am having a very difficult time installing this (and several other) plugin, and there doesn't seem to be any Installation instructions. When I uploaded the plugin, it seems to have created two versions in the Plugins sections: "Blog Types" and "Blog Types Version 2.0.0"

Version 2.0.0. cannot be installed site-wide; it produces the error: "Blog Types configuration file not found." The other plugin can be installed, but does not seem to appear anywhere to set the settings. Please help. Thanks!
