Description

When troubleshooting issues related to .NET framework, it might be helpful to find the exact .NET version in use. This article lists 2 ways to find out the .NET framework version.

Note:The Release version can be found using either of the following methods. Its value is a release key that corresponds to a particular version of the .NET Framework which can be mapped to a table listed in Microsoft documentation.

Resolution

Finding out the Release version:

1)Using the Registry editor

From the Start menu, choose Run, enter regedit, and then select OK to open the Registry editor.

Note: You must have administrative credentials to run regedit.

In the Registry Editor, open the following subkey: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full.

Note- If the Full subkey isn't present, then you don't have the .NET Framework 4.5 or later installed.

2) Using Windows Powershell command-

From the Start menu, choose Run, enter Windows Powershell, select it to open the Powershell
Use this PowerShell command to find the value of the Release and Version entry of the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full subkey
(Get-ItemProperty "HKLM:SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full").Release

(Get-ItemProperty "HKLM:SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full").Version

Once the Release version is found out map it with the table here-

.NET Framework version	Value of the Release DWORD
.NET Framework 4.5	All Windows operating systems: 378389
.NET Framework 4.5.1	On Windows 8.1 and Windows Server 2012 R2: 378675 On all other Windows operating systems: 378758
