Installation of IBM SPSS Amos 21 or 22 requires Microsoft .NET Framework version 4.0
Installation of the IBM SPSS Amos 21 application on a Windows system may bring up the following error message:
"The Microsoft.Net Framework Version 4.0 was not found on your machine. This is required for the Amos installation to continue. Please install the Microsoft.NET framework first."

With the upgrade to IBM SPSS Amos 21 or 22, Microsoft .NET Framework Version 4.0 is now a required prerequisite.
Please note that you must install the full setup of Microsoft .NET framework 4.0 (dotNetFx40_Full_setup.exe).
On Windows 7 operating systems the preinstalled Microsoft .NET Framework 4 Client Profile (version 4.0.30319) is NOT the full, extended setup of the framework and not sufficient for the AMOS installation. For AMOS you need the full setup of .NET Framework 4 Extended (version 4.0.30319.
