[wix-users] C++ custom action, Visual Studio 2015, Windows XP/Windows Server 2003

[David Connet]

Are you specifically targeting XP? All compilers after vs2010 do not support XP by default. (You must use Platform Toolset "<platform>_xp" [v140_xp in this case]) That's the link Phill pointed you to.

Ok, I will be more specific. We have an installer that has quite a few C++ custom actions, statically linked to C runtime, of course. Initially it was built with VC++ 2010, and then upgraded to 2012 and now 2013. A few days ago we upgraded it to VC++ 2015 and some of the custom actions started failing with "Return value 3".
