Hi,
I have a Dell inspiron 5521 core i5 3337U laptop. I am using windows 7. I had the same problem. And even I was unable to install .NET framework also. But after seeing your advice I was able to install .NET framework only. But still there is problem with the AMD driver. When I try to install intel HD drivers, a message displays saying that "This computer does meet the minimum requirements for installing the software " When I submit my service tag, the intel HD drivers are not recommended for my laptop. What should I do now?
