We have both Windows and Macintosh workstations. Do we need to install a special way?

In order to run cross-platform with SE 1.x, you will need to perform a workstation SE install on a Windows client first and then install the Macintosh clients.

If you have been running with all Macintosh clients and later add one or more Windows client workstations, you must already have Windows license codes. You can then add a level to install the Windows license codes from a Windows client workstation.
