Dexterity Shared Components 10.0 installation Error

During the installation of MS Dynamics - Great Plains 10:
Component Installation window has everything marked off with a green check mark except the 
"Microsoft Dexterity Shared Components 10.0".  When I click the Install button, it tries to
install the "Microsoft Dexterity Shared Components 10.0" but it fails.
Error message pops up stating, "Initialization failed. Review the log file for more details: C:\DOCUME~1\Ramzy\LOCALS~1\Temp\log8.tmp".It says is 
"ERROR: One or more components failed to install correctly."
I researched it on the Internet, it says uninstall the Microsoft .NET FrameWork 2.0.
When I tried to uninstall the FrameWork2.0, I have this error: 
Microsoft .NET Framework 2.0 Service Pack 1 cannot be uninstalled 
because it will affect other applications that are installed. 
This error occurs when you have installed also the higher version of .NET FrameWork 
either version 3.0 or 3.5.
Before you can uninstall the .NET Frame Work 2.0 you should uninstall first 
from higher version down to lower version. 
e.g. from 3.5 then 3.0 then 2.0.
After uninstalling .NET Framework2.0 restart the PC.
Reinstall again the Great Plains.
