problem. Ensure that you properly installed and configured the program. If necessary, uninstall and then reinstall the program.

operating system environments.

instructions.
Ensure that you have not made an error while entering data — See the program documentation to make sure that the values or characters
you are entering are valid.
Check for viruses — Use a virus-scanning program to check the hard drive, floppy disks, or CDs.
Restart the computer — Save and close any open files, exit any open programs, and then shut down your computer through the Start menu
