It's because you have and older version of Microsoft Sql server compact Edition that conflict with my local installation, to rectify the problem need to do is:

1. Download http://www.microsoft.com/downloads/en/d ... 0b323dce24
2. Uninstall the application.
3. If you are running a 32 bit OS then install only the 32 bit version.
4. If you are running a 64 bit then install both of them.
5. Reboot.
6. Re-install the application
