I am trying to install patch 9.2.0.6.0 to a DB 9.2.0.4.0. I keep getting an error message:
Ceratin files which need to be reinstalled by oracle universal installer are being used by one or more applications

I closed the database, stopped all oracle services, iis service distributed transaction coordinator.
Does anyone know where I can get a list of all applications it may be talking about?

Thanks
