Installing Dynamics AX 2009 Client on Windows 7

When I try to install Dynamics AX 2009 Client on Windows 7, the installation failed with the following error:-
RegAsm : error RA0000 : Could not load file or assembly 'System.Design, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.
Install: During Setup of an error occurred. Program run: C:\Windows\Microsoft.NET\Framework\v4.0.30319\regasm.exe. Parameters: C:\Program Files\Microsoft Dynamics AX\Common\MindKeyGroup.MindKey.Wheel.dll /unregister
This looks strange to me because Windows 7 is certified for running AX 2009 Client. After looking into details of the error, it seems that .NET Framework v4.0 is used during the installation.
I uninstalled the Microsoft .NET Framework 4 Client Profile and install again the AX 2009 Client. The installation then was successfully.

I was tearing my hair out, trying to solve this problem.

Your solution helped me understand the compabibity issues with .net4.0 and AX2009. Now the installation follows through
(after removal of .net4.0)


Thank you!
