Before You Begin

You can install the Oracle VirtIO Drivers for Microsoft Windows by using the GUI installation program or by performing a silent installation. Use the graphical installation program if you are installing a single instance of the Oracle VirtIO Drivers for Microsoft Windows. If you plan to silently install multiple instances of the Oracle VirtIO Drivers for Microsoft Windows, you must run the GUI installation program in a command line window on at least one Microsoft Windows guest to create a response file. You can then use the response file to perform all subsequent installations silently.

To install the Oracle VirtIO Drivers for Microsoft Windows:

1. Copy the Oracle VirtIO Drivers for Microsoft Windows installation program Setup.exe to the guest.

2. Start the installation by running Setup.exe in one of the following ways:

   • To perform a single installation, double-click Setup.exe to start the Oracle VirtIO Drivers for Microsoft Windows installer.

   • To record a response file for automated installations on multiple systems:

     1. Open a command line window.

     2. Navigate to the directory where the Setup.exe file is located.

     3. Run Setup.exe -r to start the Oracle VirtIO Drivers for Microsoft Windows installer and create a response file for silent installations.

3. If prompted, select Yes in the User Account Control dialog to allow the Oracle VirtIO Drivers for Microsoft Windows installer to proceed.

   The Welcome window is displayed.

4. Click Next.

   The Start to install Oracle VirtIO Drivers for Microsoft Windows Release 2.2 window is displayed with information about your selection.

5. Click Install to start the installation.

   The installer copies the Oracle VirtIO Drivers for Microsoft Windows files and installs the drivers on the guest.

6. After the installation completes, click Finish.

   The virtual machine is restarted.

   Note:

   If you are migrating Windows guests from Oracle Cloud Infrastructure Classic to Oracle Cloud Infrastructure, shut down the Windows guest VM in the Oracle Cloud Infrastructure Classic environment and then start the Windows guest VM in the Oracle Cloud Infrastructure environment.

The Oracle VirtIO Drivers for Microsoft Windows are installed in the following directories:

• On 32-bit systems: C:\Program Files\Oracle Corporation\Oracle Windows VirtIO Drivers

• On 64-bit systems: C:\Program Files (x86)\Oracle Corporation\Oracle Windows VirtIO Drivers

If you used the -r option in the command line, the installation program creates a response file in the C:\Windows directory. You then use the response file, setup.iss, to perform silent installations on other Microsoft Windows guests. See Silently Installing or Upgrading the Oracle VirtIO Drivers for Microsoft Windows.
