SQL Server 2008 R2 installation Error code 0x84B40002.
When I try to install Microsoft SQL Server 2008 on a Windows 7, the installation fails. When I try to reinstall SQL Server 2008 on the same system, this installation also fails.

I referred an article no. 955404 in support.microsoft.com.

After following all the mentioned steps, i.e., is up to the step "setup.exe /ACTION=uninstall /FEATURES= /INSTANCENAME=", I received a new error. The error is as follows:

1 solution

One possibility is that there is some installations existing in the system that prevent a clean install/re-install, such as beta versions etc.

Try uninstalling the existing SQL Server manually from that system and after that run the silent install.

You can follow for example these instructions http://support.microsoft.com/kb/909967[^] which basically also apply to your version.
