Find installed .Net Framework Versions

There is three quick ways you can find the installed .Net Framework versions on the any given computer.

1. Use IE and JAVA Script to find the user agent string.

This will ONLY works in IE. Open IE and type javascript:alert(navigator.userAgent). The pop-up window will have the information of all installed .Net Framework versions.

2. Check the Registry by yourself

Open RegEdit.exe and navigate to

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP

NDP has the major versions of installed .Net Framework software. Expand one of the keys and you can find out full version number.

3. Powershell

Open Poweshell and copy/paste the following script.  Thanks Richard for the above script which I found it HERE.

Get-ChildItem 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP' -recurse | Get-ItemProperty -name Version -EA 0 | Where { $_.PSChildName -match '^(?!S)\p{L}'} | Select PSChildName, Version

PS C:\Scripts> .\dotNetFrameworkVersions.ps1
