WinXP/Win2k Registry

I develop VBA and VB solutions.

One of my apps, a Word add-in, has stopped working on PCs loaded with WinXP. I realize that WinXP locks down everything by default unless logged in as administrator.

It appears that even the VBA registry keys (where I store various program settings) are also locked out when logged in as a restricted user.

What is the best way to deploy VBA and VB templates and EXEs in WinXP so that I can make the registry and shortcuts to my apps available to all users (or a select group)?
