Replace In Search Window

When I right-click on a drawing in my search window and select SolidWorks I now see Replace and Rename along with Pack and Go in EPDM2010 where-as in EPDM2008 I only have Pack and Go.  Please see attached image.

When I click on the Replace I get a license agreement popping up for Workgroup.  We do not have Workgroup we have Enterprise.  Before I accept the agreement can anybody tell me what the Replace and Rename actually does?  Also if I accept the agreement is it going to install workgroup or anything else?  No-where can I find any documentation in regards to this.

Thanks,

Bill
