Resolve issue with DISM "missing" or with the 32-bit DISM being called on a 64-bit system

Recently while creating a chocolatey package, I ran into an issue where trying to install a windows feature would fail on my 64-bit windows operating system with a message saying that I could not use the 32-bit version of DISM to manage features. The reason this was happening was because of the 32-bit redirection that occurs on a 64-bit operating system. I also found an issue (#378) that seems to be related because either the DISM was not in the path or more likely it was due to the lack of a new line between the closing curly brace and the "cmd" and resulted in "none" of the code being executed in the elevated shell.

After reading the "contributing" document, I implemented the fix in a branch and sent a new pull request.
@jberezanski this is where you are talking about right?
