Managed to somewhat like this and it will return all the running process:

MIDL

Process[] wordProcs = Process.GetProcessesByName("WINWORD");
if (wordProcs.Length > 0)
{
   foreach (Process wordProc in wordProcs)
    {
      if (wordProc.MainWindowTitle != "")
        {
           //Do something here
        }
    }

}

Each version of the COM library will most likely have access to only those instances from the same version. So if you have 2 versions of Office, you'll probably need to COM interop with them separately.

In response to your comment:

Yeah you'll need separate assemblies that link to specific interop versions. And maybe a common assembly that can then act as the sync-ing point.

I have 2003, 2007, 2010 office version. For ex, if i open PPT one by one, program detects the instance. But when all three versions documents are open, it fails to get the instances. I am using Microsoft.Office.Core version 14.0 and 12.0 com interops.
