quickly find out which version of the .NET framework is installed on a system

This is something I have answered several times to many people, anything from production personnel to network administrators

is quite easy (the yucky using the mouse way)

You go to the control panel, Add or Remove Programs, wait forever for that to populate the list, then go find "Microsoft .NET Framework X.X"

if you want to do it quicker than that, you can use this method instead:

open a folder to:


or whatever the equivalent on your machine is, like


first of all, if the folder c:\windows\Microsoft.NET doesn't exist, then you don't have any .NET framework version installed

Then, if you do get to that folder, you should see some folders like




That's the version of the .NET framework installed (the first two digits matter the most)

It's also important to note that just because the folders exist there it doesn't mean that version is installed, to make sure you would actually have to go inside the folder and see that it has a ton of files (100+) and about 6-10 folders

for ~95%+ of the cases though, I just type c:\WINDOWS\Microsoft.NET\Framework\v at the "run" window and see what shows up and that works just fine
