SQL Server 2005 backward compatibility setup

Good Day,

I am having trouble installing the SQL Server 2005 backward
compatibility
component. The install is failing with an error message and not
creating an
install log, as far as I can tell. The install fails "because a higher
version
already exists on the machine". But as far as I can tell no other
version
exists on the machine.

Here is the message:

Installation of Microsoft SQL Server 2005 Backward compatibility
failed
because a higher version already exists on the machine. To proceed,
uninstall the higher version and then run Microsoft SQL Server 2005
Backward compatibility setup again.

The file name is sqlserver2005_bc.msi
I downloaded it from:
http://www.microsoft.com/downloads/details.aspx?FamilyID=d09c1d60-a13c...79-9b91

There is no mention of the install in the application log or the SQL
log.
My guess is that the setup program read a registry key and determined
that the component was already installed. But the component is not
already installed.

The SQL Server is SQL Server 2005 Enterprise Edition build 9.00.3282.

Has anyone encountered this before? Any idea how to fix?

Thanks,

-Terry

First, I suggest you to check Add\Remove Programs list for Microsoft SQL
Server 2005 Backward Compatibility and if it's installed then uninstall it.
You have probably tried this but I should mention it before suggesting the
following way.

If it does not seem to be installed then download and install Windows
Installer Cleanup Wizard and uninstall Microsoft SQL Server 2005 Backward
Compatibility in case you find it in the list.

Those two tools probably look for the same registry keys, but the second
suggesttion saved many lives before =)
