Unregister DLL using regsvr32

Question

This is driving me nuts.

I registered a DLL (COM) using

regsvr32 blabla.dll

In the meantime, I deleted this DLL manualy from disk.

How can I unregister this dll? I know the CLSID.

Edit:

Apparently I need to delete this from the registry.

What should I delete in the registry?

Answer 1

The unregistration code lives in the DLL, unfortunately, so regsvr32 /u blabla.dll won't work; you'll need to manually delete the DLL's information from the Windows registry using regedit. I believe that the registration information is typically located in HKEY_CLASSES_ROOT\CLSID\{YOUR-CLSID}.

Answer 2

Another way of fixing this is to put the dll back and unregister it. Then you can delete it.

We often have this at customers places with midas.dll where the registered path does not have the dll.
