In my basic MSI setup I have a SetupType dialog in which the user choose the configuration ( Cleant, Server, WEB etc. ) Then according to the chosen configuration I use the MsiSetFeatureState to enable\diable features and show the all features in the CustomSetup dialog, ( I'm also trying to hide unneeded features but that's a diffetent story )
Than according to the choose of sub-features in the CustomSetup I'm using MsiSetFeatureState again to diable\enable sub-features but it seems that the setup ignore this part and install all sub-features. MsiSetFeatureState(hMSI,"N_CLIENT\\N_PD\\MicrostationInteg\\MICROSTATION_J",INSTALLSTATE_ABSENT);
I think MsiSetFeatureState just wants the "leaf" feature name ("MICROSTATION_J") and not the whole subfeature tree; in MSI, internal feature names are unique, unlike features/subfeatures in InstallScript projects.
You might also be able to make use of Add and Remove control events, which might save you the trouble of creating custom actions...
