When installing QuickBooks, it is very much common to end up in QuickBooks error 4120. This error is often seen with an error message that says “QuickBooks has encountered a problem and needs to be shut down without any further explanation”. As we mentioned earlier, the user can end up in such an error when trying to install the QuickBooks software with the latest release. Such an error can be seen if the operating system is corrupt or if the Microsoft components required by QuickBooks desktop aren’t either working properly or are corrupt. The consequences of such an error can be software malfunctioning and also the software and the system might respond sluggishly. The system might crash, freeze, or hang after the error appears.
