The NBO heading echoes any requested keywords (none for the present default cas ) and shows an estimate of the memory requirements (in double precision words) for the separate steps of the NBO process,  compared to the total allocated memory available through your ESS process. Increase the memory allocated to your ESS process if the estimated NBO requests exceed the available storage."

the application of this solution, to my ESS program, is the subject of this message. My ESS program is ADF.

Dear May Abdelgani,

The memory used on ADF is irrelevant for your purpose. In fact ADF will use memory automatically as it needs to. Since ADF does not need to be directly interfaced with NBO in the same way Gaussian does for some specific jobs like NCS and the like, the only thing you need is a FILE47 and NBO will run self-sufficiently.

Since the NBO 3.0 version is very old, you'll need to recompile the program to allocate a larger memory, since in 1990 the use of memory was very modest.

Have you tried using my precompiled binary for Windows ? I remember increasing the MEMORY key to a higher value when I compiled it:
