[wix-devs] Question about Merge Modules using WIX

Personally I would create a burn bootstrapper and redist the vcredist.exe version of your runtime instead.  I've had a lot of pain with third party merge modules over the years.

If you really do want to use the merge modules,  realize you can't  really change their behavior  so  the way you'd go about it is associate the merge module to an optional feature and use appsearch / feature conditions to control the installation request state of the feature and thereby the installation of the components  merged in by the merge module.

But honestly... a bootstrapper bundle is the safer way to go IMHO.

Subject: [wix-devs] Question about Merge Modules using WIX


I am new to WIX and I am trying to do the following task.

We are installing VC++ redistributables as per the following document.

How To: Install the Visual C++ Redistributable with your installer - WiX toolset<http://wixtoolset.org/documentation/manual/v3/howtos/redistributables_and_install_checks/install_vcredist.html>
How To: Install the Visual C++ Redistributable with your installer. If your application depends on the Visual C++ runtimes you can include them as part of your installer to simplify the installation experience for your end users.

But I want to only ADD these redistributables( merge modules) if they are not already present.
How can I accomplish that?

Any help would be appreciated.
