Install Using Wise 6 merging BDE

Hello everybody,

 I am attempting to create an install program using Wise 6 on an application
containg the BDE. My worry is that I will override existing BDE settings on
any install on a PC which contains an application already using the BDE. Has
anyone any experience of installing into an environment such as this and
enabling some function or code / script which will merge the BDE
configurations, thus not upsetting any resident application ?

Many thanks to anyone who replies
