InstType without custom
I want to use InstType to tell user if it is an installation or an upgrade. So then I will have:
InstType Installation
InstType Upgrade
InstType /NOCUSTOM
I just want two possible choices, but only one of them will be visible. I will detect in advance if it is an installation or an upgrade.
But then I have some trouble to select/deselect sections at the same page. Is it possible to tell the installer to not change value in InstType dropdown even if the user select/deselect sections? And the user should be able to pick free which sections to select on both installation and upgrade.
Anyone who understand what i like to do?
