Hi guys, i have reinstalled win7 on my inspiron 3521 recently. Unfortunately network driver (and some others) don't want to install. Log keep saying that vendor software returned code 7. Can someone give me a guide of that driver or provide a solution?

(I also tried to install win10 and everything worked well except freezes)
