MSSQL 2005 Vs. Visual Studio 2005 Service Pack 1

Hi,
for some reason, when I've installed visual studio 2005, I didn't install also SQL server.
Than I've updated VS with Service Pack 1 (thank god, I was trying unsucesfully for about 2 weeks :/ ).

Than I want to install MSSQL 2005 and an error came up:

Message displayed to user
SQL Server 2005 Setup has detected incompatible components from beta versions of Visual Studio, .NET Framework, or SQL Server 2005. Use Add or Remove Programs to remove these components, and then run SQL Server 2005 Setup again. For detailed instructions on uninstalling SQL Server 2005, see the SQL Server 2005 Readme.
SQL Server Setup has detected that the following required component is not installed: Microsoft Windows Installer 3.1. To proceed, download and install the Windows Installer 3.1 Redistributable from http://go.microsoft.com/fwlink/?LinkId=50380 , and then run SQL Server Setup again.

1. The http link leads to main page of MS Download Centre.
2. I have Installer 3.1. (version of file c:windowssystem32msiexec.exe said so)
3. I really do not have any beta version of any mentioned SW. I never had.

So I think the issue could be, that installer is checking for not updated version of Visual Studio.
(I was searching through net/msdn and seems no one had this problem (maybe wrong keywords, though) ).

I'm running setup.exe from CD1.

Uninstalling of VS Service Pack 1 is not an option. I really don't want to spent another week by installing it.
Please tell that there is some another way :) .
Thanks a lot.

Here are some logs:
