Download & Install VirtualBox Extension Pack on Windows 10/8.1 Host

Whenever Oracle releases updates for their best and free virtualization software VirtualBox, you must update the extension pack to get extra features on the guest virtual machine. If you use some of the advanced features such as USB 3.0/2.0, VirtualBox RDP and PXE boot for Intel cards inside a virtual machine on Windows 10 or 8.1 host, then you must upgrade VirtualBox extension pack to the latest version. This small guide shows how to download and install VirtualBox extension pack on Windows 10/8.1 and Windows 7 host machines.

We have earlier published few guides on installing VB guest additions on Windows 10 and how you can use VirtualBox to install and test Windows 2012 R2 server at your home PC.  Normally if you open a saved or new virtual machine without updating the extension pack, you will get an error message informing about USB2.0/USB3.0 and extension pack issue. The particular virtual machine can’t be resumed without removing some of the configurations or updating the extension pack to the latest version.

If you want to start the virtual machine without installing the latest extension pack, you can simply disable USB2.0/30. support under VM settings as below.

As shown below, if you select USB 2.0 or 3.0 support without having the latest extension pack, you will get the following warning message.

Two Methods to Install VirtualBox Extension Pack

What is Inside?

Method 1

Download the file from above link. It would be in ‘vbox-extpack’ file extension format in Windows 10/8.1.  Once you open the file, VirtualBox would open and ask for installation. Click install to start the installation on Windows 10, it will be updated automatically if you have the previous version.

You must have the administrative privilege to run this package on a Windows computer. Even you can right-click the file and select ‘Run as Administrator’.

Method 2

Go to File –> Preferences in the menu, then select Extensions option in VirtualBox console. From here you can browse the downloaded extension pack and install it on Windows 10.

You can view the previously installed extension packages in the same place. Uninstalling an extension package can be done here by selecting the pack and click remove button.

This installation will fix the warning message of USB 2.0/3.0 support on Oracle VirtualBox and now you should be able to start new or saved virtual machines without any issues. Another few additional features will be available now. USB 3.0 feature will allow your guest virtual machines to access the data faster from the attached physical USB drives/Disks on a host computer.

  1. Thanks for the tutorial. I had an error when I tried to install it. It’s saying that the installer failed to rename the temporary directory to the final one: VERR_ACESS_DENIED…

    What am I doing wrong?

  2. I had the same issue. Allowing the extension manager to run in administrator mode changes the error to (VERR_UNRESOLVED_ERROR) for the VBoxExtPackHelperApp.

    I uninstalled the previous 4.0.2, removed the leftover Extension Pack and reinstalled 4.0.4. This did not help and the error is still the same.

    Extension pack version and file name is: Oracle_VM_VirtualBox_Extension_Pack-4.0.4-70112.vbox-extpack

  3. I had the same issue.

    so i think i gonna uninstall this update because its a total failing !!!
    the older worked perfectly, lets reinstallin it so !

  4. Solved:

    – Open a command prompt as Administrator : Right-click on “AccessoriesCommand Prompt” and choose : Run As Administrator.
    – CD C:Program FilesOracleVirtualBox
    – Make sure the ExtensionPack is located in the same directory
    – C:Program FilesOracleVirtualBox>VBoxManage.exe extpack install Oracle_VM_Virt

    C:Program FilesOracleVirtualBox>VBoxManage.exe extpack install Oracle_VM_VirtualBox_Extension_Pack-4.0.4-70112.vbox-extpack
    Successfully installed “Oracle VM VirtualBox Extension Pack”.

  5. Gracias! este tutorial realmente me funcionó, es muy práctico y descriptivo por lo que resultó sencillo arreglar el molesto problema al restaurar la máquina virtual

  6. In my Mac OS X 10.6.4 guest, there was an error “The USB device could not be mounted”. What I am trying to mount is a Sandisk Cruzer. Any ideas?

  7. Just my 2cents:
    I had troubles in re-installing Oracle_VM_VirtualBox_Extension_Pack-4.1.0-73009, as well as uninstalling it. Several attempts, both from the GUI and from the VBoxManage command line, ended with some VERR… error.

    In the end I managed to successfully uninstall and install again that extension pack from the command line, with following commands:

    “\Program Files\Oracle\VirtualBox\VBoxManage.exe” extpack clean

    “\Program Files\Oracle\VirtualBox\VBoxManage.exe” extpack uninstall “Oracle VM VirtualBox Extension Pack”

    “\Program Files\Oracle\VirtualBox\VBoxManage.exe” extpack install “Your\Path\To\Oracle_VM_VirtualBox_Extension_Pack-4.1.0-73009.vbox-extpack”

  9. Thank you, thank you, thank you, this was THE ONLY SITE THAT FIXED my problem…I had gone to at least 10 site or more to “try” to download Oracle_VM_VirtualBox_Extension_Pack for windows 10….I cannot phantom WHY MS and Oracle make it so hard to install something so basic? Nevertheless I am grateful for this site and I am going to KEEP this extension pack for later use for VM.
