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 You can use the installation file from the CD that is a part of your box edition but this file might be out-of-date.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 rec ommended getting the latest installation file online. You can download the file from the AVG website (at http://www.avg.com/download?

prd=msw)

Note: There are two installation packages available for your product - for 32bit operating systems (marked as x86) and for 64bit operating systems (marked as x64). Be sure to use the correct installation package for your spec ific operating system..

During the installation process you will be asked for your license number. Please make sure you have it available before starting the installation. The number can be found in the CD pac kaging. If you purc hased 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 and read the license conditions. Use the Printable version button to open the license text in a new window. Press the Accept button to confirm and continue to the next dialog.

A V G Email Server E dition 2 0 11 © 201 0 Copyri ght A VG T ec hnologies CZ, s.r.o. A ll rights res erved. 8

Attention: You will be able to choose also additional languages for the application interface later during the installation process.

3.2. Activate Your License

In the Activate your License dialog you have to fill in your license number.

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.

Press the Next button to continue the installation process.

3.3. Select Installation Type

The Select type of Installation dialog offers the choice of two installation options: Quick Install and Custom Install.

For most users, it is highly recommended to keep to the Quick Install that installs AVG in fully automatic mode with settings predefined by the program vendor. This configuration provides maximum sec urity combined with the optimal use of resourc es. In the future, if the need arises to c hange the configuration, you will always have the possibility to do so directly in the AVG applic ation.

Custom Install 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.
