Lisa, Best way is that u can write a custom action at uninstall which checks whether other two products r installed or not... set a property for tht
if it found other products then it means tht shared files wont get deleted from target machine. and u can populate messagebox accordingly (as per the property value) at the end of the installation On Tue, Mar 9, 2010 at 2:11 PM, Lisa Gracias <lisathelugubri...@gmail.com>wrote: > I have 3 msi's which contain the same merge module.
