Important Note: Its always prudent to make a backup of your data file before you update. To do this open the software and go to Administration and the Data file management tab. If you are installing because you can't open the software, you can copy your data file manually by going to the MyDirectoryMakerSchool folder and copying the MyDirectoryMaker_Data.accdb file to a personal folder.
