I am attempting to install a named instance of SQL 2005 dev edition.
The target machine already has several named instances of SQL 2012.
Setup of SQL 2005 failed with the error "An installation package for the product Microsoft SQL Server Native Client cannot be found".
This error apparently occurs because a newer version exists from the 2012 install. However, uninstalling native client and attempting to install SQL 2005 again then fails with a similar error, but this time for the VSS writer.
This page http://msdn.microsoft.com/en-us/library/ms143694.aspx indicates that it should be possible to install SQL 2005 on a machine that already has SQL 2012 installed, but what I am seeing is that I will need to uninstall rather a lot of components
of the 2012 install (probably breaking those instances) before installing SQL 2005.
Is there a workaround for this that does not involve breaking all existing 2012 instances?
