Details:

I'm a little afraid this is another manifestation of bug #51152

COM objects (ActiveX objects) do not accept arguments, sometimes not even
parentheses enclosing the argument(s). 
I hit this when investigating io package problems while invoking Excel through
ActiveX.  If needed I can show how to reproduce the bug with LibreOffice, but
then I'd need to search & undig some old scripts.  But the bug can simply be
demonstrated with Notepad.exe as well.

Steps to reproduce:

* install and load windows package
* then:

>> app = actxserver ("WScript.Shell")
app =

<COM object IWshShell3 (0x0x11def570)>

>> app.run ("NOTEPAD.EXE", 3)
error: com_get: property/method invocation on the COM object failed with error
`0x80020003'


Expected result (here with Octave-3.9.0+ I still had installed):

>> app = actxserver ("WScript.Shell")
app =

<COM object IWshShell3 (0x0x8861768)>

>> app.run ("NOTEPAD.EXE", 3)
ans = 0


(the latter hidden behind a full-screen Notepad window. Just use Alt-tab to
get to the Octave terminal)
To close the app object, do File | Exit in Notepad and in Octave just:
delete (app);
