Share VM's with other users in version 6?

I have the problem described in KB 5733: I need to move the VM to a "Users/Shared/Parallels" folder on the boot drive. ( I have set up a new SSD boot drive and moved my home folder to a separate hard drive to save space on the SSD. Parallels says I don't have sufficient rights to configure the vm's in my old home folder). I have tried to follow the instructions for KB 5733, but the v. 6 options are different. Locate doesn't show up until I try to start a vm in the list window, which then says it is missing and to click "Locate" to browse to it. I browse to a copy of it I placed in the boot /users/shared/parallels folder, but the "Choose" button stays grayed out when I highlight the parallels folder.

How do you do this in Desktop 6?
