Hi, for those of you, like me, who had problems installing Zimbra getting messages like "zimlets not intalled" and "can't connect to zimbra server" --

uninstalling is not enough! you have to track down the files and delete them manually. i uninstalled and reinstalled several times to no avail. when i manually deleted the folders (I had to go to "local folders", which for some reason is hidden when i get the default view) zimbra started no problem

this is not complex, just requires full uninstallation/deletion of all current zimbra files you have on your computer before trying again.

i hope this saves someone some time...
