Notes:
-
On Windows 7 systems, the .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.
-
The [!INCLUDEnet_v45] is supported on the Windows Preinstallation Environment (Windows PE). Not all features are supported on Windows PE.
-
The .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 the Windows Update website to ensure the best compatibility and security.
-
On 64-bit operating systems, the .NET Framework supports both WOW64 (32-bit processing on a 64-bit machine) and native 64-bit processing.
