I have one application which runs fine on other windows version except Windows 8. On windows 8 I am getting error for .net framework 3.5 not installed. As It is in prerequisite list in my windows installer . So when I select check box, It will start installing but then its throwing error So I want to know whether the source of .net framework set up for windows 8 is different then other? Or What should I do to include correct setup in installer which works fine on every version including windows 8.
