I have a disabled daughter and we use Publisher to produce all of her communication boards. We purchased an iMac, installed Parallels, Windows 7, and then installed Publisher 2003 (same as the PC). I transferred all of the Publisher files from our PC (back up is available). Publisher will load, and I can access the files in Z drive. However, when I try to open, the following message appears: Publisher cannot load files from a different version. My assumption is that Parallels and Windows 7, will not operate Publisher 2003. Does anyone have a solution please as we need this program to support my daughter.
