(Solved) Installing Avast! Business Protection Plus from Avast 4 SBS Edition

Hello,
A few years ago, I installed Avast 4 SBS Edition on a server Windows with twenty workstations.

The current server OS: Windows Server 2003 for Small Business Server SP2.
The desktop OS to date: XP Pro or Windows 7.

The current version of the antivirus installed on the server: Avast 4.8 Server Edition.
Additional patches: ISA Server, MS Exchange, and SMTP

On the desktop, there is Avast 4 pro (stand alone) or NetClient installed via the console ADNM of the time.

Today, when renewing licenses, the dealer made ​​me buy licenses
for “Avast! Business Protection Plus” that should allow me to update my installation.

problems:

How do I make the update of my server, knowing that the version
installed does not accept the new license?

To be more precise, should I uninstall version 4.8 of my server and NetClients of my desktop before installing ?

But perhaps there is somewhere a manual for use “that goes” to enable us
(poor user that we are) not to spend tens of hours trying in vain
installing this software without crashing our server.
I found a manuel! but in English and I am a headache flanks. There is nothing in French? And there is no response for my first question.

Thank for your help

(translated with google)

you have to uninstall the ADNM and install the SBC product
its not an upgrade
there is a manual, even in french its mentioned the SBC FAQ sticky
hence the FAQ (Frequently Asked Questions)

Thank you very much,
I look at it next Monday. :smiley: :smiley: :smiley:
