SQL 2008 with Visual Studio 2008 setup failed !!!

Some SQL Server 2008 features install components of Visual Studio 2008 SP1 and because VS 2008 does not support the execution of VS 2008 and VS 2008 SP1 on the same computer; the setup program of SQL Server 2008 will not be able to complete due to this rule.
to resolve this issue you have to do one of the following actions :

• install Visual Studio SP1 before SQL Server 2008
• uninstall Visual Studio 2008, install SQL Server 2008 than Visual Studio 2008 and Visual Studio 2008 SP1
• install SQL Server 2008 without the following components
• Management Tools
• Integration Services
• BI Development Studio
