How to check whether a dll or ocx has been registered?


A

AP

Please advise a quick way to verify manually whether a dll or ocx has been
correctly registered. By searching the dll in the regedit many entries may
be found. How do I know that they are correctly registered?

Hi AP,
If you want to make sure a .dll or ocx file is registered, it does
no harm to register it again using:

regsvr32.exe myfile.ocx

....at the command prompt.

Hi,

Thank you for your post.

Before moving on, I would like to let you know all registered COM class
objects are listed under HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\. We can
navigate to this location in registry editor, highlight CLSID and press
Ctrl+F to search the dll/ocx file.

For more information, please refer to the following article:

In addition, all registered COM class objects have particular GUID, you can
try to use OLE/COM Object Viewer to check it. This tool is included in
Windows Server 2003 Resource Kit Tools.
