How reinstall DRWEB in my Plesk

Hello

I need reinstall drweb in my plesk 9.5.4-ubuntu8.04.build95101209.08

How to know if I have a license drweb?
Where I can download the package to reinstall?

Thanks and regards.

Some steps related to this are:
Login to the VPS Hosting/server & execute "uname -i" to get the OS bit version so that you can download the appropriate installer package
[root@server ~]# uname -i
x86_64
Later on, run "cat /etc/redhat-release" to check the name & version of the OS installed on the system, for downloading the appropriate installer package.
[root@server ~]# cat /etc/redhat-release
CentOS release 5.2 (Final)
