[wix-users] How to install 2 components with same file content with one difference

Don't worry about it. Smart cabbing will prevent any duplication in the source media and separate mutually exclusive Components per-OS are totally reasonable here.

Subject: [wix-users] How to install 2 components with same file content with one difference

Hello Wix-Users

I am looking at different options on how to install the same Windows driver on both Server 2016 and Windows 10. The installation part works well, but Server 2016 does NOT offer the same functionality to uninstall.

Before writing a CA to uninstall a driver on Server 2016 which will use SetupDiRemoveDevice from the SetAPI, I was wondering if I can do this using purely wix functionality.

- difx:driver works well on server 2016 but is deprecated in the later versions of Windows 10. Under Windows 10 I now use a CA that calls DiUninstallDriver from newdev.dll, that uses a reference INF, This is not supported in server.

So here is my plan, but I don't think Wix supprts this. Ideally I would have one component that install on both OSes then on Windows 10 have my CA run and Server 2016 have difx run based on the one component, but from what I understand it's not how difx works, it needs to be in its own component.

Any advice?

   <DirectoryRef Id='INSTALLFOLDER'>
      <Directory Id="DriverFolder" Name="MyInstaller" >

        <Component Id='Windows10Driver'   Guid='Place GUID here'
Win64="yes">
         // All my driver files listed here
          <File Id='---'  Name='DriverFiles.sys' DiskId='3'
Source='PathToMyFiles\DriverFiles.sys' KeyPath='no'/>	
          <Condition>ISWINDOWS10 = 1</Condition>
        </Component>

        <Component Id='WindowsSrv2016Driver'   Guid='Place GUID here'
Win64="yes">
         // All my driver files listed here (SAME FILES AS ABOVE)
          <File Id='---'  Name='DriverFiles.sys' DiskId='3'
Source='PathToMyFiles\DriverFiles.sys' KeyPath='no'/>	
          <difx:Driver AddRemovePrograms="no" Legacy="yes"
PlugAndPlayPrompt="no" Sequence='1' />
          <Condition>ISSERVER2016 = 1</Condition>
        </Component>

      </Directory>
    </DirectoryRef>

Thanks for your help,
Marc
