Setup Errors on Visual Studio 2008

Recently I uninstalled my VS 2008 and tried to install VSTS 2008. Unfortunately I was blocked by a couple of setup errors. Thus, I found a couple of good links/tools.

Generally speaking, if we want to uninstall VS 2008 and reinstall a new VS 2008, we can use the tool of Windows Install Cleanup to remove the components described in the link  https://go.microsoft.com/fwlink/?LinkId=85096. That cleanup tool is very fast.
