Installation

Once a Theme has been delivered to a device [via Bluetooth, Infrared, USB cable], the installation process is straight forward and similar to that used in installing Symbian OS application.
The Theme .sis package is installed by either opening the Theme package from the messaging application or locating the .sis file on the memory card. When the package is opened, the standard S60 installer handles the Themes installation.


If you get certificate error when attempting to install 3rd party software on your S60 3rd Edition smartphone, it means that you haven't enabled installation of unsigned SIS files. Go to Tools -> App. Manager, choose Options -> Settings and set Software installation to All and Online certif. check to Off.
