I'm not sure if this is how I'm supposed to post, but I saw a thread entitled, "Help with os.spawnv", that I wanted to respond to. I believe if you change the variable pyScript from: "E:\\Documents and Settings\\Administrator\\Desktop\\Ian\\GIS\\Python\\subProcess2.py" to '"E:\Documents and Settings\Administrator\Desktop\Ian\GIS\Python\subProcess2.py"' (this basically uses a single backslash and a single quote preceding the first double quote and a single quote just after the last double quote). your script would work.
