There are two steps to fix this issue:

Step 1. 
You need to make sure the Language for non-Unicode programs under 'Region' on your computer is set to English (United States).

On Windows 7
From the search box in the bottom left corner type the word "Region" and hit enter then select "Region and Language".

On Windows 8, 8.1, and 10
From the windows tile menu (aka START screen) or from the search box in the bottom left corner just start typing the word "Region" then select the icon that looks like a globe with a clock in it named Region.

Step 2.
After the OS specific steps, follow these instructions:
Click on 'Administrative' Tab ->
click on the "Change system locale" button under the Language for non-Unicode programs section and make sure it is set to English (United States).
