Prerequisites to Running the OEE12Setup.exe Program
Tools Release 9.2.2 Considerations. The OUI installer delivered by Tools Release 9.2.2 is upgraded to a newer version of OUI itself. You may encounter issues if you use a newer version installer to install a package on an existing Development Client installation that used the older version installer. Although not required, Oracle highly recommends that the older Development Client installation either be uninstalled or saved using Snapshot before running a new installer. Furthermore, the new installer for 9.2.2 requires an uplift to the latest JRE/JDK as listed in the Oracle Certifications for the Development Client.
The OEE12Setup.exe program is used to install the local Oracle 12c
            database. This program is called from the InstallManager program when you click on this
            link:
EnterpriseOne Database Engine
Optionally you can also manually launch the OEE12Setup.exe program to
            perform optional functions. In either case (InstallManager or manually), prior to
            running the OEE12Setup.exe program, ensure that this Microsoft Windows
            system variable either does not exist, or if it does that it points to a valid JDK:
JAVA_HOME
Otherwise, the OEE12Setup.exe program will fail to execute and return an
            error stating the JDK is invalid.
For instructions on launching InstallManager to install the local Oracle database with default parameters, refer to the section entitled: Using InstallManager to Install a Local Database.

                instructions on manually launching the OEE12Setup.exe program to

                this guide entitled "Running OEE12Setup.exe from the Command
