I downloaded Media Go 2.4 to my Xperia Z Tablet, but I can't open it. When I click on it, it says "the file cannot be opened". Do I need to download something else first for 2.4 to work on my tablet?
Media Go is an application that is installed on Windows operating systems. You can't open it using your phone because Android doesn't recognize Windows installers as being recognized or supported files. You need to install Media Go on the PC then use it to synchronize it with tablet.
Android will never recognize this application since it's not available in the APK format, therefore it will display the error message. You need to install Media GO on your computer, then you can use the application to perform sync operations.
