  4. Run the Oracle Universal Installer (OUI) in .\Disk1\setup.exe to install the software.
  5. After installation of the OUI update is completed, install any required Oracle data access components, such as Oracle Data Provider for .NET and Oracle Objects for OLE. The installer requires each data access component to be installed one at a time.
  6. After the installation, delete ODAC92070.exe and the temporary installation folders and files.
