Access Developer Extensions and Office 12

I have an Access database that was designed in Access 2003. I also have the
Access Developer Extensions (2003 – 11.0.5622).

I just recently installed Office 12 on my laptop but I have Office 11 on my
desktop. I tried to use the Packaging Wizard on my laptop but received the
following error message:

- dataroot
- Error

Three questions:
Does this mean the Developer Extensions will not work with Office 12, and
that I cannot create a package on my laptop?

Does this mean that if I used the Packaging Wizard on my desktop with Office
11 (also on my desktop) that the ultimate package could not be installed on a
computer that had Office 12 on it?

Has there been another Developer Extensions issued that I don’t know about,
and if so, how do I acquire it?

Thank you for any insight you can provide. It would be so nice if these
could all play well together...
