How to Register All OCX Files

OCX files are Windows ActiveX controls.

Windows requires that all ActiveX controls be entered into the system registry before use. ActiveX controls are represented by files with the extension OCX. If you'd like to register the OCX files on your hard drive, you have two options. You can either manually register all of your OCX files using the "RegSvr32" command, or you can download software that will register multiple OCX files with a single command.

Instructions

Register OCX files manually

1. Click on the "Start" button and select "Search for files or folders." This opens up a search window.

2. In the search box, type "*.OCX" to find all OCX files on your computer.

3. Click the "Start" button again and select "Run" to open up the command-line run window.

4. Type "RegSvr32 filename" in the run box and press "Enter," where "filename" is the name of the first OCX file located in your search window. This will add that OCX ActiveX control to your system registry. For example, to register "Example.OCX" you would type "RegSvr32 Example.OCX" in the run box.

5. Repeat Step 4 for each OCX file that is listed in your search window.

Use a program to register OCX files

1. Download a program capable of registering your OCX files automatically. RegDllView is one program that is capable of registering many OCX files with a single action (see download link under Resources).

2. Click on the "Start" button and select "Search for files or folders." This opens up a search window. Type "*.OCX" in the search box to find all of the OCX files on your computer.

3. Open the RegDllView program. If you are running Windows 7 or Windows Vista, you will need to right-click on the program and select "Run as Administrator."

4. Highlight all OCX files in your search window.

5. Drag and drop the OCX files from your search window into the RegDllView program window. The RegDllView program will create entries for all of the OCX files in your system registry.
