Hello! Are you implementing using a third party or consulting resources?
Recently we have seen some cases where customers no longer have a windows installation. After the initial install and configuration, once the instance has gone live, the windows install is either deleted or most likely no longer with the customer as the same was installed on the implementers' laptop to start with. As a result when support comes back requesting the customer to apply a patch and/or upgrade they do not have a windows installation. This has started happening after Oracle Demantra gave them the option to configure the engine on Unix.
It is advisable that the customer keep their Windows installation intact for further patching and/or upgrade. It is aslo possible that the implementer had installed Demantra on his Windows box and you do not have access to it any more. It is possible that with the web and engine on Unix, and the silent installer having downloaded all the executable for Business Modeler, to work on the User's client machine, you may no longer need the windows install.
I have not tested the above
