Symptom:  TimeGuard would not run on Windows 7 or Vista, showing error messages.

Solution:  Try to run TimeGuard with additional administrator rights.
Most compatibility issues are solved by running TimeGuard with additional administrator rights. By default, an application is not started with those additional rights, but this can be done manually by right clicking the shortcut to the application and selecting Run as administrator . Those administrator rights can also be added by default, by right clicking the shortcut to the application, selecting  Properties---> Shortcut tab---> Advanced button and activating the option Run as administrator.
This procedure should be repeated for the 3 TimeGuard shortcuts with orange star icon . One is found on the desktop , one found in 'Start--->All Programs--->TimeGuard', and the one found in 'Start--->All Programs--->Startup'.
