How to know the ..NET Framework version installed on your machine

Issue :  

Its a common practice among Webserver Administrators to find out the exact version of .net framework installed on their IIS box. It can be found in the properties of Application Pool in IIS manager. But you can find only the main version of .Net Framework there like 1.1, 2.0, 3.0, 3.5, 4.0 etc.

If you need to know the exact version of .NET Framework like (4.5, 4.6, 4.61, 4.7 etc) the above mentioned way can not help. 


Solution : The best and most authentic way to know the exact version of .NET Framework installed on your machine is : 

1. Log on to server with Admin rights.
2. Go to Run
3. Type : Regedit
4. It will open registry editor.
5. Go to following path under HKEY_Local_Machine : 

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET FRAMEWORK Setup\NDP\V4\Full

6. Click on "Full" key and at the right hand pane you will find another key with name "version"
7. This key contains the exact version number of .NET Framework 4 installed on your machine.
