|
|---|
| 8 | To avoid popups when performing an unattended installation
|
|---|
| 9 | of the <ph conkeyref="vbox-conkeyref-phrases/product-name"/> Guest Additions, the code signing
|
|---|
| 10 | certificates used to sign the drivers needs to be installed
|
|---|
| 11 | in the correct certificate stores on the guest operating
|
|---|
| 12 | system. Failure to do this will cause a typical Windows
|
|---|
| 13 | installation to display multiple dialogs asking whether you
|
|---|
| 14 | want to install a particular driver.
|

| 15 | </p>
|

| 16 | <note>
|
|---|
| 17 | <p>
|
|---|
| 18 | On some legacy Windows versions, such as Windows 2000 and
|
|---|
| 19 | Windows XP, the user intervention popups mentioned above
|
|---|
| 20 | are always displayed, even after importing the Oracle
|
|---|
| 21 | certificates.
|
|---|
| 22 | </p>
|

| 23 | </note>
|
|---|
| 24 | <p>
|
|---|
| 25 | Installing the code signing certificates on a Windows guest
|
|---|
| 26 | can be done automatically. Use the
|
|---|
| 27 | <filepath>VBoxCertUtil.exe</filepath> utility from the
|
|---|
| 28 | <filepath>cert</filepath> folder on the Guest Additions
|
|---|
| 29 | installation CD.
|
|---|
| 30 | </p>
|
|---|
| 31 | <p>
|
|---|
| 32 | Use the following steps:
|
|---|
| 33 | </p>
|
|---|
| 34 | <ol>
|
|---|
| 35 | <li>
|
|---|
| 36 | <p>
|
|---|
| 37 | Log in as Administrator on the guest.
|
|---|
| 38 | </p>
|
|---|
| 39 | </li>
|
|---|
| 40 | <li>
|
|---|
| 41 | <p>
|
|---|
| 42 | Mount the <ph conkeyref="vbox-conkeyref-phrases/product-name"/> Guest Additions .ISO.
|
|---|
| 43 | </p>
|
|---|
| 44 | </li>
|
|---|
| 45 | <li>
|
|---|
| 46 | <p>
|
|---|
| 47 | Open a command line window on the guest and change to
|
|---|
| 48 | the <filepath>cert</filepath> folder on the
|
|---|
| 49 | <ph conkeyref="vbox-conkeyref-phrases/product-name"/> Guest Additions CD.
|
|---|
| 50 | </p>
|
|---|
| 51 | </li>
|
|---|
| 52 | <li>
|
|---|
| 53 | <p>
|
|---|
| 54 | Run the following command:
|
|---|
| 55 | </p>
|
|---|
| 56 | <pre xml:space="preserve">VBoxCertUtil.exe add-trusted-publisher vbox*.cer --root vbox*.cer</pre>
|
|---|
| 57 | <p>
|
|---|
| 58 | This command installs the certificates to the
|
|---|
| 59 | certificate store. When installing the same certificate
|
|---|
| 60 | more than once, an appropriate error will be displayed.
|
|---|
| 61 | </p>
|
|---|
| 62 | </li>
|
|---|
| 63 | </ol>
|
|---|
| 64 | <p>
|
|---|
| 65 | To allow for completely unattended guest installations, you
|
|---|
| 66 | can specify a command line parameter to the install
|
|---|
| 67 | launcher:
|
|---|
| 68 | </p>
|
|---|
| 69 | <pre xml:space="preserve">VBoxWindowsAdditions.exe /S</pre>
|
|---|
| 70 | <p>
|
|---|
| 71 | This automatically installs the right files and drivers for
|
|---|
| 72 | the corresponding platform, either 32-bit or 64-bit.
|
|---|
| 73 | </p>
|
|---|
| 74 | <note>
|
|---|
| 75 | <p>
|
|---|
| 76 | By default on an unattended installation on a Vista or
|
|---|
| 77 | Windows 7 guest, there will be the XPDM graphics driver
|
|---|
| 78 | installed. This graphics driver does not support Windows
|
|---|
| 79 | Aero / Direct3D on the guest. Instead, the WDDM graphics
|
|---|
| 80 | driver needs to be installed. To select this driver by
|
|---|
| 81 | default, add the command line parameter
|
|---|
| 82 | <codeph>/with_wddm</codeph> when invoking the Windows
|
|---|
| 83 | Guest Additions installer. This is only required for Vista
|
|---|
| 84 | and Windows 7.

|
|---|
| 88 | <p>
|
|---|
| 89 | For Windows Aero to run correctly on a guest, the guest's
|
|---|
| 90 | VRAM size needs to be configured to at least 128 MB.
