Windows 8 comes preinstalled with .Net Framework 4.5 which would mean that it should work for applications that are based upon .Net Framework 3.5. But that’s not the case. Tools that require the latter version sometimes fail to initialize the installation just because they can’t find the specific framework on your computer.
Moreover, you can’t install .Net Framework 3.5 manually as the installer will prompt you that a newer version is already installed on your system. So let’s see how you can resolve this deadlock and enable .Net Framework 3.5 on Windows 8 to install dependent software.
