Can't install dll to windows/system32 about wixsharp HOT 6 CLOSED

Yes it seems to be broken for cases without sub-folders. Use direct WiX constants instead:

var project = new Project("MyProduct",
            new Dir("SystemFolder", new File("MyLibrary.dll")));

from wixsharp.

I don't know why, but your sample doesn't install MyLibrary.dll in system32.
The code below works well:

var project = new Project("MyProduct",
            new Dir(new Id("SystemFolder"), "System", new File("MyLibrary.dll")));

from wixsharp.

My bad, I forgot, it's not the name it's Id that controls the destination path for the WiX constants for spacial folders.

Your work around is exactly what is needed.

The problem is caused by the auto-assignment INSTALLDIR id to the bottom-most directory, which is in your case happens to be a special folder that needs to keep its original Id.

Thus the alternative work around to set the auto-id value to the string of your choice:

Compiler.AutoGeneration.InstallDirDefaultId = "SystemFolder";

from wixsharp.

As an enhancement added compile warning on special folder dirId reassignment.

I was trying so hard to create subfolder under the SystemFolder and keep getting duplicate id until I found this as suggested by the owner.
Compiler.AutoGeneration.InstallDirDefaultId = "SystemFolder";
