I've gotten 3 multiprocessors up and running... here's what I did.
1. First, I uninstalled the gui version,and deleted any directories, that had the console version.
2. Created a directory called FAH
3. Under FAH, created a subdirectory for each processor, called FAH1, FAH2, etc
4. Downloaded the console client executable into the subdirectories.
5. Going to each subdirectory at a time, launched the client, and if you're not duplicating, the first time you launch it, it will go into configuration mode.
6. Follow the on-screen menus, and then when it asks you for advanced, make sure that you say yes. Continue with the defaults, until it comes to where it asks you for machine ID. For FAH1, enter 1, FAH2, enter 2....
7. Leave the cmd box open, until you've finished configuring all of your processors. In the explorer box, for that processor, you'll notice that the program creates several log files, and a work directory.
8. Close the cmd boxes, and then under control panel, find administrative tools, and services.
9. In the services windows, right click on the first FAH entry, and then properties. in the bottom window, "run variables", put a -local Apply, and then right clicking again, start the service. Repeat for your other FAH entries.
10. You can check the progress, by browsing to these FAHx and FAHy directories, and clicking on the FAHlog... and it will tell you current progress, and what run#, etc it is currently working on.
Not as nice as the gui, but far more efficient.
Ahhh... good, very *nix-y steps :o) Wish I'd gotten your advice a bit sooner--I got it working by uninstalling all FAH programs and then installing the console, and then installing the GUI afterwards. The console program had been looking for the GUI's work path in the registry keys. Yours is quite a bit more neater, though, and I'll probably need them if the console starts looking in the registry keys at every bootup, rather than just at the install.
