Make 2 folders with super pi in (you need 1gb of ram or more to run dual 32m), name 1 folder 'super pi 1' the other 'super pi 2'. Open a copy from each folder. Got to task manager, right click one of them and set to core 0, do the same for the other but set to core 1.
I guess your sig is wrong or you just wanted to run two?
Edit: Just realised you do not need to set affinity just put them in diferent folders
