If you install a file that contains an update or repair to an
existing application, you can only restore the original
application if you have the original installation file or a
full 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.
To install an application, do the following:
1 To locate an installation file, select 
Menu
 > 
Settings
 and
Application mgr.
. Alternatively, search installation files
using File manager, or select 
Messaging
 > 
Inbox
, and
open a message that contains an installation file.
2 In Application manager, select 
Options
 > 
Install
. In
other applications, select the installation file to start the
installation.
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. If the application does not
have a default folder defined, it is installed in the Installed
apps. folder in the main menu.
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
Ovi 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.
