|

|
|---|
| 7 | <p>To avoid popups when performing an unattended installation of the <ph
|
|---|
| 8 | conkeyref="vbox-conkeyref-phrases/product-name"/> Guest Additions, the code signing certificates used to sign
|
|---|
| 9 | the drivers needs to be installed in the correct certificate stores on the guest operating system. Failure to do
|
|---|
| 10 | this will cause a typical Windows installation to display multiple dialogs asking whether you want to install a
|
|---|
| 11 | particular driver. </p>
|
|---|
| 12 | <note>
|
|---|
| 13 | <p>On some legacy Windows versions, such as Windows 2000 and Windows XP, the user intervention popups mentioned
|
|---|
| 14 | above are always displayed, even after importing the Oracle certificates. </p>
|
|---|
| 15 | </note>
|
|---|
| 16 | <p>Installing the code signing certificates on a Windows guest can be done automatically. Use the
|
|---|
| 17 | <filepath>VBoxCertUtil.exe</filepath> utility from the <filepath>cert</filepath> folder on the Guest Additions
|
|---|
| 18 | installation CD. </p>
|
|---|
| 19 | <p>Use the following steps: </p>
|
|---|
| 20 | <ol>
|
|---|
| 21 | <li>
|
|---|
| 22 | <p>
|
|---|
| 23 | Log in as Administrator on the guest.
|
|---|
| 24 | </p>
|
|---|
| 25 | </li>
|
|---|
| 26 | <li>
|
|---|
| 27 | <p>
|
|---|
| 28 | Mount the <ph conkeyref="vbox-conkeyref-phrases/product-name"/> Guest Additions .ISO.
|
|---|
| 29 | </p>
|
|---|
| 30 | </li>
|
|---|
| 31 | <li>
|
|---|
| 32 | <p>
|
|---|
| 33 | Open a command line window on the guest and change to
|
|---|
| 34 | the <filepath>cert</filepath> folder on the
|
|---|
| 35 | <ph conkeyref="vbox-conkeyref-phrases/product-name"/> Guest Additions CD.
|
|---|
| 36 | </p>
|
|---|
| 37 | </li>
|
|---|
| 38 | <li>
|
|---|
| 39 | <p>
|
|---|
| 40 | Run the following command:
|
|---|
| 41 | </p>
|
|---|
| 42 | <pre xml:space="preserve">VBoxCertUtil.exe add-trusted-publisher vbox*.cer --root vbox*.cer</pre>
|
|---|
| 43 | <p>
|
|---|
| 44 | This command installs the certificates to the
|
|---|
| 45 | certificate store. When installing the same certificate
|
|---|
| 46 | more than once, an appropriate error will be displayed.
|
|---|
| 47 | </p>
|
|---|
| 48 | </li>
|
|---|
| 49 | </ol>
|
|---|
| 50 | <p>To allow for completely unattended guest installations, you can specify a command line parameter to the install
|
|---|
| 51 | launcher: </p>
|
|---|
| 52 | <pre xml:space="preserve">VBoxWindowsAdditions.exe /S</pre>
|
|---|
| 53 | <p>This automatically installs the right files and drivers for the corresponding platform, either 32-bit or 64-bit. </p>
|
|---|
| 54 | <note>
|
|---|
| 55 | <p>By default on an unattended installation on a Vista or Windows 7 guest, there will be the XPDM graphics driver
|
|---|
| 56 | installed. This graphics driver does not support Windows Aero / Direct3D on the guest. Instead, the WDDM
|
|---|
| 57 | graphics driver needs to be installed. To select this driver by default, add the command line parameter
|
|---|
| 58 | <codeph>/with_wddm</codeph> when invoking the Windows Guest Additions installer. This is only required for
|
|---|
| 59 | Vista and Windows 7. </p>
|
|---|
| 60 | </note>
|
|---|
| 61 | <note>
|
|---|
| 62 | <p>For Windows Aero to run correctly on a guest, the guest's VRAM size needs to be configured to at least 128 MB. </p>
|
|---|
| 63 | </note>
|
|---|
| 64 | <p>For more options regarding unattended guest installations, consult the command line help by using the command: </p>
|
|---|
| 65 | <pre xml:space="preserve">VBoxWindowsAdditions.exe /?</pre>
