Wix Installer: One feature with condition to decide which ComponentGroupRef to use

问题

My installer has a Feature called "Tools"

What is installed by this feature is dependent on which version of SQL Server the client is running.

How can I have one feature with a condition that says "If SQL 2008 do ComponentGroupRef ID=SQL2008 otherwise ComponentGroupRef ID=SQL2012"

I'm creating 2 properties to hold the directory for SQL2008 and SQL2012, so those are the properties I'm using to make my determination.

This is close, but shows "Tools" feature twice.

<Feature Id="SQL2008Tools" Title="Tools" Level="1" Description="Installs all support UI Tools for SQL 2008">
      <Condition Level="1"><![CDATA[SQL2008BINDIR AND NOT SQL2012BINDIR]]></Condition>
      <ComponentGroupRef Id="Tools2008Component"/>
    </Feature>

    <Feature Id="SQL2012Tools" Title="Tools" Level="1" Description="Installs all support UI Tools for SQL 2012">
      <Condition Level="1"><![CDATA[SQL2012BINDIR]]></Condition>
      <ComponentGroupRef Id="Tools2012Component"/>
    </Feature>

As always - thanks for any help!

As you've found the title of a feature does not have to be unique. You have two features with the same title so it shows that way.

Try using nested features:

<Feature Id="SQLTools" Title="Tools" Level="1" Description="Installs support UI Tools for SQL Server"> 
  <Feature Id="SQL2008Tools" Title="SQL 2008 Tools" Level="1" Description="Installs all support UI Tools for SQL 2008">
    <Condition Level="1"><![CDATA[SQL2008BINDIR AND NOT SQL2012BINDIR]]></Condition>
    <ComponentGroupRef Id="Tools2008Component"/>
  </Feature>

  <Feature Id="SQL2012Tools" Title="SQL 2012 Tools" Level="1" Description="Installs all support UI Tools for SQL 2012">
    <Condition Level="1"><![CDATA[SQL2012BINDIR]]></Condition>
    <ComponentGroupRef Id="Tools2012Component"/>
  </Feature> 
</Feature>
