For stand-alone GenNBO usage, just include the "ARCHIVE" and "FILE=jobname" keywords in a standard NBO-linked electronic structure job (including those from earlier NBO versions) to obtain the "jobname.47" file that allows you to run alternative analyses (without recomputing the wavefunction) from the convenience of your PC/Mac/Linux laptop or desktop.
Alternatively, simply include binary NBO7 in the environment of your NBO7-compatible host ESS to see the cooperating ESS/NBO7 binary pair "come to life" through message-passing to tackle complex interactive tasks.
