I would start off first by going to your software package and remove "all additional files" and then re-add them, save it.
Now right click on the package and reset the hash.
If you are not zipping the files, etc, this can take 30 - 40 minutes to reset the hash on all files and I have been unable to find a way to tell when it is actually done.
You might want to see this thread, on page two I have listed exactly how I am deploying Office 2010
Thank you for the reply. Right clicking the package and selecting reset hash happened to fix my deployment of Office 2007. I also checked out your thread on how you deployed 2010. I plan on modifying my script to match what you ended up doing since zipping the files seems to be better than having the individual files.
Thanks again for your help!
