HI,
I never implemented this my self but try to do the following:
1. Use Minor upgrade instead of Major upgrade. (by definition Major upgrade
is completely new installation that installs everything from scratch
allowing to uninstall old versions and therefore when you choose particular
features only they get installed)
2. In some place in UI sequence* after feature selection* dialog
repopulate(write some custom action) ADDLOCAL, REMOVE and REINSTALL
properties so that:
a. ADDLOCAL and REMOVE will be empty
b. REINSTALL will contain features that user selected in dialog
3. Repopulate REINSTALLMODE property so that include "v" (this will run
installation from the source package and not from cached msi and at the end
recaches msi to new one).
I hope this should work
