i am trying to run a location allocation-minimize facility with 77 facilities and 386,221 demand points. It run for about 10 minutes, but then I get and out of memory error message. I see from other threads that this is common issue for network analysts and say that there is a way to excute a work around through chunking by changing some of the setting in the registry. However, I was about to find the correct registry option to change for my particular problem. Any sugesstions are welcome. best
