Windows unattended

Error after installation "Failed to acquire VirtualBox COM object".

This error may occur due to some error in the process after the installation of VirtualBox, which prevents the program from starting for the first time. VirtualBox C++ error

It occurs due to the occurrence of an error in the VirtualBox configuration files. To solve it we must force the program to generate these files again, to do this you must go to the user's personal folder C:\Users\{Username} and there locate the folder .VirtualBox. It is enough to change the name of this folder (it can be .VirtualBox_old) and to start the program again so that the configuration files are generated again.

If for some reason you had a virtual machine already created and it does not appear in the program, do not worry. The virtual units are in the folder you renamed, you only have to add the machines again and specify the virtual hard disk of your old machine and you will have it available again.
