What Is MSCOMCTL.OCX In Windows Systems?
These days, it is pretty common to get Visual Basic or ActiveX errors when mscomctl.ocx or one of its dependencies is not registered on your system. But, before you resolve it, you need to know what this file is all about. mscomctl.ocx is actually a control file that comes with the Microsoft Visual Basic 6.0 environment.
This OCX file mainly controls various Windows elements, such as the toolbar, image combo, and slider. Besides, some other programs and apps also need this file during installation. However, it is absolutely necessary for Visual Basic, which is a Microsoft-developed programming language. And if you don’t have the mscomctl.ocx file on your system, the Visual Basic-made programs will not start.
