How to find a COM dll installation working back from the Interop dll

Question

I have a project that references a COM dll, and the Interop assembly is available and visible in my project, but I would like to locate the actual COM dll and dependencies, so that I can build a complete deployment package.

Short of just searching the registry in Regedit, is there anything else I can do to get a grip on this COM package?

You'll always end up going to the registry. You can obtain CLSIDs from the interop, by looking for [Guid] attributes on classes. From these, you can look in HKEY_CLASSES_ROOT\CLSID\<guid>\InprocServer32 for the location of the DLL.

The OleView tool -- included with Visual Studio -- is helpful for this. One you locate your COM class under "All Objects", it can show you all the relevant registry entries in one place.

Thanks @Tim. Any idea where I can find that tool in VS 2010? – ProfK Dec 06 '10 at 13:26
Open a Visual Studio Command Prompt window and type `oleview`. I found mine at C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\oleview.exe. – Tim Robinson Dec 06 '10 at 13:27
for me, in windows 10 it was in `HKEY_CLASSES_ROOT\Wow6432Node\CLSID\\InprocServer32` – Maslow Nov 01 '16 at 16:46
