Finding the .NET Framework Version

You can view what version of .NET Framework you have installed on a given machine, by looking into the Registry Editor, as follows:

For .NET Framework 1 - 4

1. In the Start menu, type Run and click the displayed desktop app. The Run window is displayed.
2. In the Open box, type regedit.exe and click OK. The Registry Editor is displayed.
   Note: You must have administrative credentials to run regedit.exe.
3. Open the following subkey: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP.

The installed versions are listed under the NDP subkey. The version number is stored in the Version entry. In the case of .NET Framework 4, the Version entry is located under the Client or the Full subkey under NDP, or under both subkeys.

Note: The NET Framework Setup folder in the registry does not begin with a period.

For .NET Framework 4.5 and Later

1. In the Start menu, type Run and click the displayed desktop app. The Run window is displayed.
2. In the Open box, type regedit.exe and click OK. The Registry Editor is displayed.
   Note: Administrative credentials are required to run regedit.exe
3. In Registry Editor, open the following subkey: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full. If the Full subkey is missing, you do not have .NET Framework version 4.5 or later installed on the machine.

   `HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full`

   Note: The path to the Full subkey includes the Net Framework subkey, rather than .NET Framework.
4. Check for a DWORD value named Release. If the Release DWORD exists, .NET Framework version 4.5 or later has been installed on the computer.
   
   

   

   
   

The value of the Release DWORD indicates which version of the .NET Framework is installed.
