there is of course a way to put settings in your registry that will allow you to right-click on a dll or ocx file and then click Register or Unregister fromt the context menu. However, for those of you who don't like messing with your registry (or don't know how) , here's a simpler way to register/unregister:

Just find your regsvr32.exe file and place a shortcut to it in your Windows SendTo folder. Then copy it and in the Target property of the new shortcut, append a '/u' (no apostrophes) to the end of the exe name. Then you can change the names of these shortcuts to "Register" and "Unregister". Then when you right click on a file, just use the SendTo menu to perform your dirty work!

A few practical notes that tie together the tips already posted by , and and that address the follow-ups from , and .

The SendTo shortcut is a handy, low-risk quick fix (good for occasional use). The .reg/context-menu approach is more convenient long‑term but edits the registry and behaves differently under UAC and on 64‑bit Windows, so treat it as a persistent change and back up the registry first.

Troubleshooting "LoadLibrary failed" / "could not be loaded into memory": common causes are a bitness mismatch (32‑bit control on a 64‑bit OS), missing dependent runtimes (VB6/Visual C++ redistributables), lack of the DllRegisterServer export (not a COM server), file blocking/corruption, or insufficient privileges. Check architecture first, run the registration step elevated, and use a dependency tool (Dependency Walker or the modern "Dependencies" viewer) to reveal missing DLLs. If the component is a managed assembly, it won’t register like a native COM DLL — it needs to be exposed to COM by the .NET tooling or by building it with COM visibility.

Answers to ’s points, concisely:

  • To find registered COM servers look for CLSID/ProgID entries in the registry (HKCR\CLSID{...} with InprocServer32 or LocalServer32 pointing at the DLL). On 64‑bit Windows also check the Wow6432Node branch for 32‑bit registrations.
  • The key places are HKEY_CLASSES_ROOT (and HKLM\SOFTWARE\Classes), and SharedDLL info appears under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\SharedDLLs.
  • COM DLLs are native and register via exported registration entry points; .NET assemblies are managed and require registration via .NET tools or explicit COM interop configuration.
  • To inspect properties use Explorer file properties plus tools like OLE/COM Object Viewer, Dependency Walker, dumpbin/sigcheck, or IL tools (CorFlags/ILDASM/ILSpy) to tell native vs managed.

Final pointers: avoid downloading individual DLLs from random sites (security risk); prefer reinstalling the package that supplies the control. If automation is needed, use the appropriate tool for the DLL type and the correct system folder/tool for 32/64 bit.

I wanted to register the winsck.ocx using regsvr32 command, but I'm getting the error always that "Load Library failed..". Can anyone help me?
Thanks in advance.

Member Avatar for Zakian

when registering the dll's use the following command

regsvr32.exe /s dll name


also make sure you are in the directory where the dll is and needs to be registered.

No need to fiddle with your registry. Just open up Notepad, copy/paste the follow text to a new document, and save that document as a .reg file (eg DLL.REG). Make sure it does not have a .txt extension (eg DLL.REG.TXT). Then all you have to do is double-dlick on the .reg file to import it to your registry. Done. Right-click on any DLL or OCX file, and you should see the two added options, REGISTER and UNREGISTER. More elegant than using the SEND TO menu.
