If the PC TimeWatch configurator crashes when you launch it under Vista, it's because Data Execution Protection (DEP) is enabled for all programs. Enabling this option can only generate trouble with many applications. You should modify this setting as follows:
1. Open System by clicking the Start button 
, clicking Control Panel, clicking System and Maintenance, and then clicking System.
2. Click Advanced System Settings. 
If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
3. Under Performance, click Settings.
4. Click the Data Execution Prevention tab, and then click Turn on DEP for essential Windows programs and services only. If you select "Turn on DEP for all programs and services
except those I select", even if you add pctimewatch.exe to the exclusion list, the problem will persist.
