When opening Oracle VM one day, you stumble upon this message (note the error code 0x80040154):

Failed to create the VirtualBox COM object.  The application will now terminate. Callee RC: REGDB_E_CLASSNOTREG (0x80040154)

virtualbox创建COM对象失败，程序终止。召唤者 RC: REGDB_E_CLASSNOTREG (0x80040154) 。 【解决】

The Virtual Machine service isn’t running. A reinstall would probably work but there is an simpler fix:

Run Command Line or “cmd”

Type the following into the command line and hit enter (including the quotes):

chdir “C:\Program Files\Oracle\VirtualBox”

Then:

VBoxSVC /ReRegServer

And:

regsvr32 VBoxC.dll

You should see a popup window notifying you of your success. Try opening VM now, it should work.
