Running GW 8.0.2. We also run have some users who need to use the Outlook client because of integration with Saleslogix. Most of the time they can use the GW client, but there are times when they must connect to Saleslogix. The problem has arisen when GW client is installed Outlook 2010 64-bit will not run. It closes with an error as soon as you launch it. If GW client is removed from system the Outlook runs without issue.
