C:\Program Files\Microsoft SQL Server\90\Setup Bootstrap\LOG\Files
I get under filename:
SQLSetup0001_'MyComputerName'_Tools
a message:
Product: Microsoft SQL Server 2005 Tools Express Edition CTP -- Configuration failed.
MSI (s) (08:80) [19:28:46:487]: MainEngineThread is returning 1638
' Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel'
In other words: Somewhere (not to find in the programslist seen under Add/Remove Programs on the Control Panel !) on my Windows XP Pro from my previous install with VS 2005 Beta 1 there is this 'Another version of this product' that prevents my new install of MS SQL Server Express 2005 Beta 2 on my machine.
Question: Does anyone know and wants to tell me where to find 'this specific product', so I can get rid of it and continue and finish my installation of SQL Server Express 2005 Beta 2 succesfully
Much appreciation and thanks for any contribution and efforts towards this disturbing issue,
Regards,
HaskeNL

If the uninstall fails, please try manual uninstall using MSIZAP

We are also developing an uninstall tool that performs the uninstall for you. Email me at hgao@microsoft.com for a Beta copy of this tool.

I used that to remove the SS Express Tools entry from my installed program database.
Installed fine after that.
