virtualbox.org

Hey I really Need Help Fast I have to install Microsoft server and Visual studio on the virtual box for college. I was trying to install a extension pack so i could transfer files from my flash drive to virtual box. Every time i try to install the extension back I get this error "NS_ERROR_FAILURE (0x80004005)"

Access the flash drive as a shared folder. You'll find it much simpler to do. Install the GAs in the guest first.
