About OCX Files. Our goal is to help you understand what a file with a.ocx suffix is and how to open it. The ActiveX Control file type, file format description, and Windows programs listed on this page have been individually researched and verified by the FileInfo team. How to Register DLL or OCX file in Windows Registering a DLL or OCX File in Windows. By registering a DLL or OCX, users are adding the information to the registry so that Windows can use those files. The information will be in the form of a name or CLSID. This makes it easier for Windows to find the correct DLL or OCX when a function related to.

Sometimes 'application extension' files (.DLL or .OCX) must be manually registered to properly support functions in a program such as CTI Navigator. A variety of ActiveX, Automation, or 'Run-time' type errors can result when associated application extension files (also called ActiveX controls) are not registered in Windows for use by the requesting program.

File Magic은 사용하기 쉽기 때문에 빨리 시도하지 않아도됩니다. Microsoft Store에서 File Magic을 다운로드하고 OCX 파일을여십시오! Try a Universal File Viewer. If you have tried all of the other solutions for opening OCX files and nothing else works, it may be worthwhile to try a universal file viewer. DOC files use a proprietary binary format and are used by Microsoft Word 2003 and earlier. DOCX files use a newer file format referred to as Open XML, which stores a document as a collection of separate files and folders in a compressed zip package. The DOCX extension is used by Microsoft Word 2007 and later. The interface is described in the type library (TLB). Your DLL (OCX is a DLL) should contain the TLB in a TypeLibrary resource. You can extract this TLB and get the interface description. This job should also be done by OLE View. If your DLL does not contain a TLB and no TLB file is provided you won't get the interface description.

Sometimes files need to be un-registered and then re-registered to operate properly. To un-register a 32-bit Windows system file and then re-register it in a version of Windows without User Account Control (prior to Vista) or with UAC turned off (in a 32-bit version of Windows Vista, 7, or 8):
- Select Start > Run (or in Windows 8, 7 or Vista press the Windows logo key + R key )
- Type Regsvr32 /u {Filename.ocx} [There is one space both before and after /u. Do not type the {} braces. Also see note 4 below.]
- Click the OK button. A message indicating DllUnregisterServer... succeeded will appear.
- Then re-register the file by running Regsvr32{Filename.ocx or .dll} (as described above. See also note 5 below)
In a 64-bit version of Windows Vista, 7, or 8 (see note 1 above):
- Select Start > Run (or in Windows 8, 7 or Vista press the Windows logo key + R key )
- Type cd WindowsSysWOW64 Regsvr32 /u {Filename.ocx} [There is one space both before and after /u. Do not type the {} braces. Also see note 4 below.]
