This morning I integrated Microsoft Silverlight 3 into our Windows 7 build. Since we use an automated image build process, i prepared the Silverlight package for a silent install.
Here’s what you need to do to run a silent Silverlight 3 installation:
Download the latest Silverlight installation package from the Silverlight website.
You will get a silverlight.exe. Run silverlight.exe /x to extract the content
Now extract the silverlight.msp from the silverlight.7z file (you can use the free 7-Zip tool to do that).
4. Then create a batch script that has the following command: msiexec /i silverlight.msi /update silverlight.msp /qn
**Update April 2010 **This works as well.
Silverlight.exe /q /ignorewarnings /noupdate
