| + | ===== When should you update the VB? ===== | ||
| + | |||
| + | <note warning>If you are not used to installing and debugging VB, you may want to play it safe and **not update VB**. Many things are fixed in a new version, but things can also break (e.g. network access, graphics, ...) and you may have to use the VB forum to get everything working again... | ||
| + | |||
| + | It is safe to update the Linux running inside VB</note> | ||
| + | |||
| + | VB will periodically check if a new version is available. You can also check that manually by doing: //File --> Check for updates...// | ||
| + | |||

| - | * Download the latest version of VB, and the matching VB additions file from the [[https://www.virtualbox.org/|VirtualBox web site]] | + | * Click on the link that VB will display in a pop-up window when there is a new version, or download the latest version of VB from the [[https://www.virtualbox.org/|VirtualBox web site]] |
| - | * Execute the VirtualBox-NN1234-Win.exe installer | + | * If the host where you are updating VB has no network connection, you probably also want to download the matching //VB Extension Pack// |
| - | * Execute VB and download and install the updated //VirtualBox Extension Pack// if VB tells you that a new pack is available | + | * You can also download an updated version of the //User Manual// from the same page |
| - | * Do not forget to update the guest additions (see below) | + | * Make sure that: |
| + | * Your VB guest is in the //Powered Off// state (i.e. you have exited the guest with a proper Linux shut down last time you used the guest) | ||
| + | * VB is not running (e.g. you don't have an open //Oracle VM VirtualBox Manager// window) | ||
| + | * Execute the VirtualBox-vvvv-NNNN-Win.exe installer **as an Administrator** (e.g. right-click on the installer and select //run as Administrator//). | ||
| + | * Accept all the default settings | ||
| + | * Make sure you don't have another program using the network when the installer warns you about having to temporarily stop the network | ||
| + | * Choose to start VB at the end of the installation, and accept to download and install the updated //Oracle VM VirtualBox Extension Pack// when VB tells you that a new pack is available | ||
| + | * Reboot the computer if VB asks for it (otherwise, you may get weird error messages when trying to restart the guest) | ||
| + | * Start the VM, optionally [[#updating_linux|update the linux guest]] and no not forget to [[#updating_the_linux_guest_additions|update the guest additions]] | ||
