VirtualBox prompts a fatal error, creating a COM object failed [solve record]

The day before, the cousin made a virtual machine, because I want to move the version, so I installed it in the U disk. Then I forgot that the machine itself has VirtualBox installed (the official installation version), causing the VirtualBox prompting "VirtualBox prompts a serious error, the creation of a COM object failed, the application will be interrupted" error, according to the detailed instructions "callee" RC: REGDB_E_CLASSNOTREG(0x80040154)』

Workaround:

1. Run the command window (“Win+R” key, enter cmd Enter) 2. Then enter (note the path is changed to Your VirtualBox installation directory): D:\\WIN_Program\\VirtualBox\\vboxsvc.exe /reregserver3. Continue typing (also note the path to your VirtualBox installation directory): regsvr32 D:\\WIN_Program\\VirtualBox\\vboxc.dll

--------The above solution comes with a solution to other errors, and records together

『VirtualBox Tip:“Cannot access the kernel driver!” 』(Unexpected, so the solution is effective)

This problem is caused by the fact that after reinstalling the system, there is no registered component and the virtual machine is running. The solution is as follows:

Open Virtua lBox installation directory Right click on the VBoxdrv.inf file and select Install.
