[makeitwork]

Hi There

I tried to intall zimbra in a Linux machine, until i go to the set up menu stage.

cd /opt/zimbra/libexec
run ./zmsetup.pl

but for the 6) zimbra-store:

I got one option show as below

******* +License filename: UNSET

So I cant go any further, can I install it without license for trial?

Thank you.
