Longtime ZCS user, first time attempt at an ZCO install and hitting an issue

Desktop is Win7 64 bit
MS Office 2010 32 bit

zmcontrol -v: Release 7.1.0_GA_3140.RHEL5_20110329135255 CentOS5 NETWORK edition

Install went fine, but on launching Outlook, I get the following error:

"Zimbra Connector for Outlook is not compatible with this edition of the Zimbra Collaboration Server. Please visit our website to find out more."

Anyone have any ideas?
