There is an easier way to get the exact version .NET version installed on your machine from a cmd prompt. Just follow the following instructions;

  1. Open the command prompt (i.e Windows + R → type "cmd").
  2. Type the following command, all on one line:

reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP"

(This will list all the .NET versions.)

  1. If you want to check the latest .NET 4 version.
  2. Type following instruction, on a single line:

reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\full" /v version

Just type any one of the below commands to give you the latest version in the first line.

1. CSC 2. GACUTIL /l ? 3. CLRVER 

You can only run these from the Visual Studio Command prompt if you have Visual Studio installed, or else if you have the .NET framework SDK, then the SDK Command prompt.

4. wmic product get description | findstr /C:".NET Framework" 5. dir /b /ad /o-n %systemroot%\Microsoft.NET\Framework\v?.* 

The last command (5) will list out all the versions (except 4.5) of .NET installed, latest first.
You need to run the 4th command to see if .NET 4.5 is installed.

Another three options from the PowerShell command prompt is given below.

6.   [environment]::Version 7.   $PSVersionTable.CLRVersion 8.   gci 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP' -recurse | gp -name Version,Release -EA 0 |      where { $_.PSChildName -match '^(?!S)\p{L}'} | select PSChildName, Version, Release 

The last command (8) will give you all versions, including .NET 4.5.

Before going to a command prompt, please follow these steps...

Open My Computer → double click "C:" drive → double click "Windows" → double click "Microsoft.NET" → double click "Framework" → Inside this folder, there will be folder(s) like "v1.0.3705" and/or "v2.0.50727" and/or "v3.5" and/or "v4.0.30319".

Your latest .NET version would be in the highest v number folder, so if v4.0.30319 is available that would hold your latest .NET framework. However, the v4.0.30319 does not mean that you have the .NET framework version 4.0. The v4.0.30319 is your Visual C# compiler version, therefore, in order to find the .NET framework version do the following.

Go to a command prompt and follow this path:

C:\Windows\Microsoft.NET\Framework\v4.0.30319 (or whatever the highest v number folder)

C:\Windows\Microsoft.NET\Framework\v4.0.30319 > csc.exe

Output:

Microsoft (R) Visual C# Compiler version 4.0.30319.17929 for Microsoft (R) .NET Framework 4.5 Copyright (C) Microsoft Corporation. All rights reserved.
