I am playing around with Zimbra. For the install, I selected the Fedora 11 version for x64. I am running: Linux 2.6.18-164.el5 #1 SMP Thu Sep 3 03:28:30 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux When I install I get an error: This platform is CentOS5_64 Packages found: F11_64 This may or may not work. Installation can not continue without manual override. You can override this safety check with ./install.sh --platform-override I am not well versed enough to know if I can do the override install and things will be fine. Did I download the wrong version from: http://www.zimbra.com/community/downloads.html -Jason
