Third-Party VCL won't allow an application to be run from CD

I have a third-party dabase VCL that is a simple replacement for the BDE, from Unley Software. But I can't get it to run from a CD or floppy. If I develope the program from a folder on the harddrive, thats where the program expects to find the database. If I later transfer the program to my rewritable CD drive(drive E:), It won't run from there. I know where the problem lies. I connect my program to the database via the object inspector, using a property editor. I suppose i could connect the database at runtime using <minitable.table := 'd:\table.mtd'> but what if my user's drive uses a different drive letter? I can't always know which drive they use. Also what if they want to transfer the program to different media later on?
Can anyone help me solve this?
Thanx...

if your databasefile resides with your application in the same location/directory, then you could easy use at appstart (preferable on the formcreate-evenet of your mainform) something like this

minitable.table := extractfilepath(application.exename)+'table.mtd'; //maybe +'\table.mtd';

and after this open your table

Well actually I havn't tried it yet, recovering from the stress of a car accident in which I totaled my car! I also got a response from unley software. They sent me a long involved solution. It's kind of dissapointing, really. I had hoped for a short, simple solution. What I have ended up doing was just to connect the minitable and the controls at runtime and give the path as it would be on the CD ie the D: drive. Most people's CD drive will be the D: drive, but that's not gaurentteed. I wonder if i could put the minitable in a resource file? Would that work?
