Hi, i have idea for you.
Download this service manager Firedaemon Pro version with gui
Set up the folding client as ordinary(dos installation) without service installation(no /install before).
Then fire up the firedaemon and install new service for different distribfold directories. You can manually select which cpu the service uses, when making new service with firedaemon.
I've done this with dual 2,4ghz ht xeons in the past.
