In DE 6.52, the Dename and Depath environment variables had to be set on every PC, and the 2 local files “configur.dat” and “Denetwrk.ovl” had to be deleted, with a copy of these 2 files in the location specified in the DePath.

In DE 7.2, these 2 local files no longer exist. Starting with version 7, there is no more DEPATH or DENAME. The serial number and local computer name are used to uniquely identify individual workstations. You should be able to just install and run.
