Cannot reinstall Sql Server Management Express

Hi,I just unistalled Sql Management Express and now I want to install it again but the installer says the product is already installed,Can somebody help me with this

What SQL components do you still show in Add/Remove Programs? Can you click on Remove and then on Report to show the detailed list and post the contents back to the thread?

Thanks,
Sam Lester (MSFT)

Cannot install business intelligence development studio project types

Hi,I'm trying to install the project templates from bussiness intelligence development studio, but it doesn't matter which installer I use in the they're not available at all.Can somebody help me to get this installed?What is the error when trying to install?|||

I am having a similar issue. When I try to install Business Intelligence Development Studio, the installation wizard states:

The following components that you chose to install are already installed on the machine. To view a report of available options and alternatives click on Details.

When I click on details:

Name: Microsoft SQL Server 2005 Tools

Reason: Your upgrade is blocked. For more information about upgrade support, see the "Version and Edition Upgrades" and "Hardware and Software Requirements" topics in SQL Server 2005 Setup Help or SQL Server 2005 Books Online.

Build version check:

Your upgrade is blocked because the existing component is a later version than the version you are trying to upgrade to. To modify an existing SQL Server component, go to Add or Remove Programs in Control Panel, select the component you would like to modify, and then click Change/Remove.

Ideas?
