IP Address on a Virtual Machine

Hi, I'm a super noobie in regards to hacking so the solution might be pretty simple here. I tried hacking my windows 7 host with a kali virtual machine using a simple guide I found on youtube. It's a client side hack, but when I double clicked the hack file nothing happened on my kali. So then I tried pinging both systems, and pinging windows from kali worked just fine, but I couldn't ping kali from my windows host. So I'm guessing the IP-address is just wrong. I used the "inet addr" under "eth0" after typing the ifconfig command. Is that the right one? Cuz that's the one everyone used in the tutorials I've seen. Anyone know what I could be doing wrong? Thx!
