The Extension Pack enhances VirtualBox with some useful capabilities. So close down VirtualBox, download and double-click on the extension pack, and VirtualBox will launch and install it for you, upgrading any earlier version you might have. None of this requires separate installation, as the extension pack has a "vbox-extpack" file extension that's handled by VirtualBox. Essentially this allows you to run a virtual machine on one PC, while you view and control it from another: again, the manual has the full story.Īnd there's also support for remote booting a computer through emulation of the Intel PXE boot ROM with support for the E1000 network card. You also get VirtualBox Remote Desktop Protocol (VDRP) support. You'll probably need to enable the controller manually, though, as well as add filters for the USB devices you'd like to use (the VirtualBox manual has more details). It includes a USB (EHCI) controller, for instance, which should allow you to get better performance from your USB devices. Once again, the main application installed fine, but the extension pack did not.The VirtualBox Extension Pack adds useful new features to this popular virtualisation package.

I tried uninstalling VirtualBox and reinstalling from a newly-downloaded installer from the Oracle website. VBoxManage.exe: error: Context: "enum RTEXITCODE _cdecl handleExtPack(struct HandlerArg *)" at line 1158 of file VBoxManageMisc.cpp This shows you the extensions which are currently installed, and enables you to remove a package. In the window that displays, go to the Extensions category. VBoxManage.exe: error: Details: code E_FAIL (0x80004005), component ExtPackManagerWrap, interface IExtPackManager To view the extension packs that are currently installed, start the VirtualBox Manager, as shown in Section 1.6, Starting Oracle VM VirtualBox.
