References and late binding running access 2007 runtime app on XP/Office 2003 PC and mcscomctl.oxc

I have the following references selected (see screen shot)  in various access2007 runtime  applications which seem to run OK on various XP machines with Office 2003 installed.

I think this is because I am using late binding. Attached is a code snip which is using late binding

   
So I am using dim myObj as Object

rather than dim myObj As Excel.Application

The reason I am not 100% sure  is that because I cannot tell on my own test XP/Office 11 PC whether I have in the past downloaded  2007 Microsoft Office System Update: Redistributable Primary Interop Assemblies.http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=18346 (I don't think I did - it doesn't spear in the list of programs in the control panel)  BUT I do have the compatibility pack installed.


I know I downloaded mscomctl.ocx the Active X control module to the xp machine a long time ago, as I needed it for some of the applications.: -   But my understanding is I only need this if I use an actrive x control in the application. And anyway XP SP3 has since included this.

Can someone confirm that:

1. As long as I only define objects as above then that prooves I am using late binding throughout and therefore, regardless of the references I have checked in the screen shot I will have no problems with earlier versions of Office or XP regarding references.

2. The office 2007 compatibility pack has no  influence over whether the references are valid - i.e the dlls required are NOT included in the compatibility pack.

3. If 2007 Microsoft Office System Update: Redistributable Primary Interop Assemblies does not appear in my control panel Add or Remove Programs list - then it is not installed.

Thanks Lou
