I have a set of OEM disks that came with a Dell PC that I have "purged" and donated to a school. My partner "lost" the product key "sleeve" and I want to put MS Publisher on my daughter's PC. I can get to the license.txt file and the "product code" info on the original CD, but can't tell what's the correct sequence (if there is one) to install the software. Any suggestions or is the CD a flat frisbee?
