Nokia N97 - Manual (Page 111)

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.
Remove applications
You can remove applications that you have installed, for
example, to increase the amount of available memory.
Select
Menu > Settings .
1 Select Application mgr. .
2 Select Installed apps. > Options > Uninstall .
3 Select Yes .
If you remove an application, 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.
If another software package depends on the software
package that you removed, the other software package may
stop working. See the documentation of the installed
software package for details.
