  • Hi,

    I've found from this blog an application can test whether the .NET Framework 4.5 or later is installed by checking the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full folder in the registry for a DWORD value named Release. A value of 378758 means that the .NET Framework 4.5.1 is installed. This logic works correctly for the redistributable version of the .NET Framework 4.5.1. However, on Windows 8.1, the Release value is set to 378675 instead, so this logic doesn’t work on Windows 8.1.

    Best regards,

    Kristin
