How do I determine which version of .NET is installed on an endpoint?

Answer

You must have administrative credentials to run regedit.exe.

To find .NET Framework versions by viewing the registry (.NET Framework 1-4)

1. In the Start menu, click Run.

2. In the Open box, enter regedit.exe.

3. In the Registry Editor, 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.
  • For the .NET Framework 4 the Version entry is under the Client or Full subkey (under NDP), or under both subkeys.

To find .NET Framework versions by viewing the registry (.NET Framework 4.5 and later)

1, In the Start menu, click Run.

2. In the Open box, enter regedit.exe. You must have administrative credentials to run regedit.exe.

3. In the Registry Editor, open the following subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full
Note that the path to the Full subkey includes the subkey Net Framework rather than .NET Framework.

  • If the Full subkey is not present, then you do not have the .NET Framework 4.5 or later installed.
  • Check for a DWORD value named Release. This DWORD indicates that the .NET Framework 4.5 or newer is installed on that computer.
  • The value of the Release DWORD indicates which version of the .NET Framework is installed.
