Can't uninstall ZCS connector 5.10
we pushed out the 5.10 version of the connector through active directory to a small group of users. one of them started having problems with outlook, and now i'm unable to uninstall the connector. i've removed it through the add/remove programs list, removed all .zdb files and dat files and removed all "zimbra" listings in the registry.
when i try to reinstall any version of the connector it tells me either there's a newer version already installed or an older version could not be removed (depending on which version of the connector i try to install).
can someone tell me how to get 5.10 completely out of there?
