What are tdc.ocx Error Messages?

ActiveX-Related tdc.ocx Errors

tdc.ocx is considered a type of COM file, or Component Object Model, most commonly known as an ActiveX control. ActiveX controls like tdc.ocx are used by Microsoft Office Access 2010 and other software to display media-related content. Therefore, your will most likely encounter a tdc.ocx error when attempting to load an audio or video clip, or view some variety of embedded website content. Some of the most common tdc.ocx ActiveX errors include:

• tdc.ocx could not be found.
• tdc.ocx could not be loaded.
• tdc.ocx failed to load. The specified module could not be found.
• tdc.ocx failed to register. The specified module could not be found.
• Cannot find tdc.ocx.
• Component 'tdc.ocx' or one of its dependencies not correctly registered: a file is missing or invalid.
• Missing or broken reference to the file tdc.ocx.
• One or more ActiveX controls could not be displayed because either: 1) Your current security settings prohibit running ActiveX controls on this page, or 2) You have blocked a publisher of one of the controls. As a result, the page may not display correctly.
• Runtime Error 339: tdc.ocx not correctly registered.
• The file tdc.ocx is missing or corrupt.
• The Module 'tdc.ocx' Failed to load. Make sure the binary is stored at the specified path or debug it to check for problems with the binary or dependent .DLL files. The specified module could not be found.
• This program requires tdc.ocx, which is no longer included.

These OCX errors are most commonly due a missing or corrupt OCX. If your file is missing or corrupt, this could be caused by improper computer shutdown, or a malware infection, both of which could corrupt (or even delete) tdc.ocx. If your tdc.ocx is corrupted or missing, and therefore cannot be properly loaded by Microsoft Office Access 2010, this will result in an error message.

Finally, another common cause of tdc.ocx ActiveX errors can be contributed to an ActiveX-related subkey missing from the Windows registry. Broken DLL (Dynamic Link Library) references in the Windows registry can prevent tdc.ocx from registering properly, resulting in an ActiveX error. These broken references (registry keys) are usually triggered by a moved or missing file, or as a result of a leftover DLL file reference after a shared program has been uninstalled.
