2.4. Uninstall Previous Versions
If you have an older version of AVG Email Server installed, you will need to uninstall it
manually before installing AVG 9.0 Email Server Edition. You must manually perform
the uninstallation of the previous version, using the standard windows functionality.
·From the start menu Start/Settings/Control Panel/Add or Remove
Programs select the correct program from the list of installed software. Be
careful to select the correct AVG program for uninstallation. You need to
uninstall the Email Server Edition before uninstalling the AVG File Server Edition.
·Once you have uninstalled the Email Server Edition, you can proceed to uninstall
your previous version of AVG File Server Edition. This can be done easily from the

uninstall also individual server plug-ins.
Note: It will be necessary to restart the store service during the uninstallation
process.
Exchange plug-in - run setupes.exe with the /uninstall parameter from the
folder where the plug-in was installed.
e.g. C:\AVG4ES2K\setupes.exe /uninstall
Lotus Domino/Notes plug-in - run setupln.exe with the /uninstall parameter
from folder where the plug-in was installed:
e.g. C:\AVG4LN\setupln.exe /uninstall
2.5. MS Exchange Service Packs

scanning interface, you must have the Service Pack 1 (or higher) for MS Exchange
2000 Server applied on your system. Follow the link below to get the latest Service
Pack for MS Exchange 2000 Server:

recommended to keep your system as up to date with the latest service packs and
hotfixes as possible in order to obtain maximal available security.

3. AVG Installation Process
To install AVG on your computer, you need to get the latest installation file. You can
use the installation file from the CD that is a part of your box edition but this file might
be out-of-date. Therefore we recommended getting the latest installation file online.
You can download the file from the AVG website (at http://www.avg.com/download?
prd=msw).
During the installation process you will be asked for your license number. Please make
sure you have it available before starting the installation. The sales number can be
found on the CD packaging. If you purchased your copy of AVG on-line, your license
number will have been delivered to you via e-mail.
Once you have downloaded and saved the installation file on your hard drive, you can
launch the installation process. The installation is a sequence of dialog windows with a
brief description of what do at each step. In the following, we offer an explanation for
each dialog window:
3.1. Installation Launch
The installation process starts with the Welcome window. In here you select the
language used for the installation process. In the lower part of the dialog window find
the Choose your setup language item, and select the desired language from the
drop down menu. Then press the Next button to confirm and continue to the next
dialog.
Attention: You will be able to choose also additional languages for the application
interface later during the installation process.

3.2. License Agreement
The License Agreement dialog provides the full wording of the AVG license
agreement. Please read it carefully and confirm that you have read, understood and
accept the agreement by checking the I have read license agreement checkbox
and pressing the Accept button. If you do not agree with the license agreement press
the Don't accept button, and the installation process will be terminated immediately.
Use the Printable version button to open the license agreement in a new window
suitable for printing.
3.3. Checking System Status
Having confirmed the license agreement you will be redirected to the Checking
System Status dialog. This dialog does not require any intervention; your system is
being checked before the AVG installation can start. Please wait until the process has
finished, then continue automatically to the following dialog.

A V G 9.0 E mail Server E dition © 2010 C opyright A V G T echnologies C Z, s .r.o. A ll rights res erved. 1 0
3.4. Select Installation Type
The Select Installation Type dialog offers the choice of two installation options:
Standard Installation and Custom Installation.
For most users, it is highly recommended to keep to the Standard Installation that
installs AVG in fully automatic mode with settings predefined by the program vendor.
This configuration provides maximum security combined with the optimal use of
resources. In the future, if the need arises to change the configuration, you will
always have the possibility to do so directly in the AVG application.
Custom installation should only be used by experienced users who have a valid
reason to install AVG with non-standard settings. E.g. to fit specific system
requirements.
3.5. Activate AVG
In the Activate your AVG License dialog you have to fill in your registration data.
Type in your name (User Name field) and the name of your organization (Company
Name field).
Then enter your license number into the License Number text field. The license
number will be in the confirmation e-mail that you received after purchasing your AVG
on-line. You must type in the number exactly as shown. If the digital form of the
license number is available (in the email), it is recommended to use the copy and paste
method to insert it.

A V G 9.0 E mail Server E dition © 2010 C opyright A V G T echnologies C Z, s .r.o. A ll rights res erved. 1 1
Press the Next button to continue the installation process.
If in the previous step you have selected the standard installation, you will be
redirected directly to the Setup Summary dialog. If custom installation was selected
you will continue with the Destination Folder dialog.
3.6. Custom Installation - Destination Folder
The Destination folder dialog allows you to specify the location where AVG should be
installed. By default, AVG will be installed to the program files folder located on drive
C:. If you want to change this location, use the Browse button to display the drive
structure, and select the respective folder. Press the Next button to confirm.

3.7. Custom Installation - Component Selection
The Component Selection dialog displays an overview of all AVG components that
can be installed. If the default settings do not suit you, you can remove/add specific
components.
However, you can only select from components that are included in your
purchased AVG edition. Only those components will be offered to be installed

·Remote Administration component - if you intend to connect AVG to an AVG
DataCenter (AVG Network Editions), then you need to select this option.
Note: Only server components available in the list can be managed remotely!

should be installed in. Check the Additional installed languages item and then
select the desired languages from the respective menu.

3.10. Installation Completion

In this dialog you decide whether you want to activate the option of anonymous
reporting of exploits and bad sites to AVG virus lab. If so, please mark the I agree to
provide ANONYMOUS information about detected threats to improve my
security option. Press the Finish button to continue.
A new AVG Optimization Scan dialog will appear. The scanning optimization
functionality searches the Windows and Program files folders where it detects
appropriate files (at the moment those are the *.exe, *.dll and *.sys files) and saves
the information on these files. With the next access these files will not be scanned
again and this reduce the the scanning time significantly.
We recommend to use this option and run the scanning optimization process by
pressing the Optimize scanning now button.
AVG is now installed on your computer and fully functional. The program is running in
the background in fully automatic mode.
To individually setup protection for your e-mail server, follow the appropriate chapter:
