-**Notes:**
-
-- On Windows 7 systems, .NET Framework requires Windows 7 SP1. If you're on Windows 7 and haven't yet installed Service Pack 1, you need to do so before installing the .NET Framework.
-
-- .NET Framework 4.5 is supported on the Windows Preinstallation Environment (Windows PE). Not all features are supported on Windows PE.
-
-- .NET Framework 4 also supports the IA64 platform.
-
-- For all platforms, we recommend that you upgrade to the latest Windows Service Pack and install critical updates available from [Windows Update](https://support.microsoft.com/help/12373/windows-update-faq) to ensure the best compatibility and security.
-
-- On 64-bit operating systems, .NET Framework supports both WOW64 (32-bit processing on a 64-bit machine) and native 64-bit processing.
