MYOB BusinessBasics may need to be installed again after your initial installation. For example, perhaps you originally installed the Compact version of BusinessBasics and you've decided that you'd like access to help files not included in the Compact installation. You can reinstall or remove files using the BusinessBasics Setup Maintenance program.
The CD included in your BusinessBasics package includes software that installs BusinessBasics onto your computer's hard disk. You should be familiar with this process from the first time you installed BusinessBasics.
