If you have an earlier installation of the Zia/Valdez package installed, it is recommended that you remove it first (back it up if you desire) and replace it entirely with this updated package.
At the very least, we recommend you compare what you already have installed against this new package. There have been some additions (the afcads in particular) and a few deletions (files that were not required).
An example of the latter is one of the previous versions stated that you needed to install a number of RWY12 libraries and textures. This was an error - those objects that have been placed using the RWY12 program are all default items which everyone already has in the FS2004 setup.
All questions regarding the project should be directed to John J. Hogan.
