I have got the software to do everything I need except one thing as outlined below.

I am making an installer to install a large amount of data. Most of my customers will not be installing all of the data from the DVD, only some of it. It's important that I have a way of letting them go back into the installer in maintenance mode (after the first installation) and choose the "change" button, which is grayed out by default. I would like to have them be able to remove some of the features and add others. So far I haven't been able to get the change button to work, although I have got it to enable, but I can't seem to enable the functionality I need. It looks like this may not be possible since the maintenance install dialog has the "Change" button disabled by default.

Thanks for any suggestions you may have to implement this functionality!
