backup copy of the removed software package. To restore
the original application, remove the application, and
install the application again from the original installation
file or the backup copy.
The JAR file is required for installing Java applications. If it
is missing, the device may ask you to download it. If there
is no access point defined for the application, you are
asked to select one. When you are downloading the JAR
file, you may need to enter a user name and password to
access the server. You obtain these from the supplier or
manufacturer of the application.
To install an application or software:
1. To locate an installation file, select
Menu > Control
panel > App. mgr. . Alternatively, search installation
files using File manager, or open a message in
Messaging > Inbox that contains an installation file.
2. In Application manager, select Options > Install . In
other applications, to start the installation, select the
installation file.
During installation, the device shows information about
the progress of the installation. If you install an
application without a digital signature or certification,
the device displays a warning. Continue installation only
if you are sure of the origin and contents of the
application.
To start an installed application, locate the application in the
menu, and select the application.
To see which software packages are installed or removed and
when, select Options > View log .
Important: Your device can only support one antivirus
application. Having more than one application with antivirus
functionality could affect performance and operation or
cause the device to stop functioning.
After you install applications to a compatible memory card,
installation files (.sis, .sisx) remain in the device memory. The
files may use large amounts of memory and prevent you from
storing other files. To maintain sufficient memory, use Nokia
PC Suite to back up installation files to a compatible PC, then
use the file manager to remove the installation files from the
device memory. If the .sis file is a message attachment, delete
the message from the Messaging inbox.

If you remove software, you can only reinstall it if you have
the original software package or a full backup of the removed
software package. If you remove a software package, you
may no longer be able to open documents created with that
software.
