VirtualBox failed to create COM object

Virtual machine is very important, especially VBox, support VHD virtual hard disk, we learn assembly language will use

First, right-click the desktop shortcut VirtualBox, select Properties, choose the Compatibility tab, tick "Run this program in compatibility Mode",

Drop-down box, select Windows Server (Service Pack 1), and then tick "run this program as administrator" to determine. Re-open and find OK.

Two

1) Open cmd command

2) Enter the VirtualBox installation directory:"CD X:\Program files\virtualbox"

3) Run the command: " Vboxsvc/reregserver"

4) Run command: regsvr32 VBoxC.dll

5) Prompt to register DLL after successful, run normally. 64-bit Win 7 passed.

The second way is strongly recommended, because I lost the component because of the system reload
