Create 32-bit COM object from 64-bit cscript script

Question

I have a JScript script which is called by cscript. That script creates Visual Source Safe ActiveX object using new ActiveXObject("SourceSafe") code in it's internals.

Everything was ok on 32-bit windows. But on 64-bit windows I need to call 64-bit version of cscript and still use 32-bit ActiveX object (SourceSafe). 64-bit version of cscript doesn't see that ActiveX class (because 32-bit class is in 32-bit branch of windows registry).

Is there any way to create that object from 64-bit cscript? (except writing 64-bit automation adapter for SourceSafe ActiveX class)

That's not possible. Using c:\windows\syswow64\cscript.exe is the simple workaround. — Hans Passant, Feb 08 '12 at 10:12

I have created COM+ server which aggregates SourceSafe COM component (see MSDN). It took less than a minute. After that I can create SourceSafe object in out-proc server using the following simple code:

WScript.CreateObject("SourceSafe")

How it works (my understanding): COM+ 64-bit out-proc server marshals automation calls to COM 32-bit out-proc server which delegates calls to 32-bit in-proc server.
