I have installed a CentOS 4.4 ServerCD wich upgraded itself to 4.5 after the first yum. Downloaded zcs4.5.5 for RHEL4.
When I run install.sh I answer yes to all questions except for the Spell.
The installation runs fine, up to the point where zimbra-store is being installed. There it says zimbra-store installation... done and does nothing for hours.
