MacPractice Support cannot assist with this portion of the configuration. For instructions on mapping a network drive, please visit Microsoft's support site: http://windows.microsoft.com/en-US/windows7/Create-a-shortcut-to-map-a-network-drive
You need to map the WindowsBridge shared folder (which should appear as a networked folder) to the H:/ drive.
Your Mac (synched with the Heidelberg) is currently on a separate computer and will need to have its IP address manually setup so that the mapped network drive from the PC will point to the IP address of the shared folder.
It would be a good idea to share the WindowsBridge folder that mounts when MacPractice is launched. This will ensure that when we extract the installer to that folder we can also just run it from there as well from the PC computer.
