OCX files are a program file extension and allow Windows users to perform common tasks such as resizing windows and moving the scroll bar. They are also referred to as ActiveX Controls or OLE (a technology for linking and embedding objects into other documents and objects) Control Extensions. OCX is also used in the programming kit. With their help, developers can implement additional functions into the program, such as displaying a million colors in the program or improving the Internet connection. By installing a program containing OCX files, the operating system registry will automatically install and register them. If you get an error about OCX files, or just want to make sure the OCX files are registered correctly, do it yourself. Read on to learn how to register OCX files on a Windows computer.
Step 1. Find the OCX file you want to register
Open the folder with the file if you know where it is stored, or run a search.
- To find a file in Windows XP, first open the Start menu and then click on Search. When the Search Companion dialog box appears, click on Files and Folders. Enter your search criteria and click Find.
- To find the file in Windows 7, open the Start menu (Windows logo) in the lower left corner of the window. When the pop-up window appears, enter your search criteria in the field at the very bottom, and then click on the magnifying glass icon on the right to start the file search.
Step 2. Select the OCX file you want to register
Hold down the Shift key on your keyboard and right-click the OCX file. When the pop-up menu appears, click "Open With …".
