PC Suite for Nokia 9290

You can download or transfer a software package containing the files of the
application into the communicator. Then you can install the application. Software
can also be installed from a memory card. A software package is usually one large
compressed file containing many component files.

communicator, use only packages whose file names end '.sis'.
An example of a suitable file name is 'MediaPlayer.sis'.
To start the installation, press Install new on the Installed software page. Browse for
the software package you want to install, and press OK. The installation process begins.
WARNING: Only install software from sources that offer adequate protection
against viruses and other harmful software. To help you, the software

signatures and certificates on software packages. See page 35.
If you are installing software without a digital signature or a certificate, the
communicator warns you of the risks of installing software, as shown in Figure 13.
