There can be a requirement when a particular program which you want to install or run on your computer requires a particular version of framework and you may or may not have that framework version installed. In such case you would like to check that whether that framework is already installed so that you can save your time and internet bandwidth as both would get wasted if you already have that software installed on your machine.
There are many small programs which finds out, one of them we had reviewed earlier called Detect DotNet, We have also written a tutorial to find out whether an application which requires some .net version pre installed will run on your computer.
