You're basically going in the wrong direction. You've converted a Visual Studio setup to WiX but you're trying to carry that VS custom action framework into WiX. The VS framework that calls managed code custom actions involves calling a C++ binary that then tries to load a NET runtime then use reflection to get into your assembly, instantiate classes and call methods. Apart from the fact that the InstallUtil Dll is transparent, undocumented and architecture dependent (you need either the 64-bit version or the 32-bit version) and therefore impossible to debug in cases like this, nobody actually bothers to propagate all this stuff into the WiX world because there are much better alternatives. For example if you're using installer classes to install services you don't need them at all. See ServiceInstall and ServiceControl. For generic custom action calls into managed code use the DTF managed code custom action framework.
