12 hours to download iTunes

i just purchased a new Toshiba Laptop, Intel i3 windows 8.1. I have been trying to download iTunes for over 24 hours now. After about 15 hours it got to 71%, but it hung there for hours than told me it had been suspended and would not restart. I am now trying it on another laptop and it is still telling me 12+ hours. I have AT&T DSL speed 6mb. I have even plugged in the Ethernet cable to see if it will go faster, but it is still crawling, any suggestions? This is so frustratiing! It shouldn't take this long to download 145mg.
