This error is often encountered when registry entries are corrupted or there is something wrong with the installation. Another problem could be caused by the compatibility issues. If you're using a higher version other than the supported one, you will encounter issues. However, a re-installation of the software could easily fix the problems you're facing. If you knew that you have installed another program and then the actual utility died, please uninstall it because it may be in conflict with the Address Book software.
