not compatible program 7.2.0 database 7.2.1

Yes thats correct

Well, clearly your application is loading the Jiwa 7.2.0 assemblies and not the Jiwa 7.2.1 assemblies.

Have a read of How the Runtime Locates Assemblies.

Two things to note :
1) if you have a .config file for your .NET application you can change the binding behaviour - check and perhaps you might opt to create one to override the bindings
2) You can put Jiwa assemblies in the GAC as they are strongly named - if you've done this previously it will use those instead of assemblies in the same folder as your application

Thanks Mike

Will give this a try
