If the ID badge software fails to start, it will most likely indicate that it is unable to find one of its component parts. The ID badge software installs and uses many files and if any one of them is missing it will not run. Some files are stored where you loaded the ID badge software and others are located in the windows and windows\system directories.
The best solution is to completely reinstall the ID badge software from the original distribution disks. This will return the required files to their directories.
