If you run into a problem opening the downloaded file of the pronunciation trainer, the first thing to do is:

  1. Find out what operating system you are using on your computer. For example, are you using Windows or Mac? What is the version you're on;  Windows 8 or Windows 10 or Mac OSX?
  2. What language do you have your computer set on?  Are all the menus and settings in your operating system in the English language or in another language? Is the main language of your computer in English or something else?

If the file reads "invalid" it is likely a compatibility issue with either your operating system or the language the your computer is set to. 

The reason the error occurs is because some operating systems are not compatible to open up the Zip files that have the content in them. If you are using the built-in Zip program that comes with your operating system, sometimes it may fail to open the file due to compatibility reasons.

The way to fix this is to use another Zip program instead. There are free to use Zip programs available online. We suggest using the free software 7zip for all operating systems, which you can get here: http://www.7-zip.org/download.html
