uninstall

Hello,

I am relatively new to WiX. It is a great tool, but I still need some time to learn it better. I have encountered a problem with registration and unregistration of a COM component. I have created installers for two applications, lets call them A and B. Both are using the same COM component. I have used the heat tool, as recommended. When installing A or B, the component is registered without any problems.

But when I install A and B, then remove A (with Add/Remove programs) the COM class gets unregistered and B cannot use it anymore. Is there a clean solution to prevent this from happening? I would like to unregister the COM when BOTH A and B are uninstalled.

Any help would be appreciated,

Best regards, madbadger
