Files downloaded from other locations are not marked as "executable" since they did not get installed via a trusted software repository.

Software in Ubuntu needs to be "executable" (sometimes called "trusted"), both in the sense that the software is a program, and that it is marked as an "executable file" via file permissions. Normal software is available for installation via the Software Center; this is the primary source of software in Ubuntu.
