Actions:
• Most software programs have built-in help systems that provide instructions for most tasks. If you are
having difficulty performing a specific task within a software program, refer to the help system for that
program. Help systems are typically accessible from a menu or button in the program, and frequently
from the F1 key.
• If you have difficulty with the Windows operating system or one of its components, refer to the Windows
help system.
• To determine if problems are caused by newly installed software, verify that:
– Your computer has the minimum memory requirements needed to use the software. See the
information supplied with the software to verify memory requirements. (If you just installed an adapter
or memory, you might have a memory-address conflict.)
– The software is designed to operate on your computer.
– Other software works on your computer.
– The software you are using works correctly on another computer.
• If you received any error messages while using the software program, see the printed documentation
supplied with the software or the help system for that software for a description of the messages and
solutions to the problem.
• Check with your software manufacturer to see if any updates are available. Many software manufacturers
make updates available from the World Wide Web.
• If the software program used to work correctly, but does not work correctly now, do the following:
1. Open Control Panel by doing one of the following:
– For Windows 7: Click the Start button to open the Start menu, and then click Control Panel.
– For Windows 8.1: See "Accessing Control Panel on the Windows 8.1 operating system" on page

– For Windows 10: Right-click the Start button to open the Start context menu, and then click
Control Panel.
2. View Control Panel using Large icons or Small icons, and then click Recovery ➙ Open System
Restore.
3. Follow the instructions on the screen.
• If you are unable to resolve the problem through other methods, uninstall the software program and
reinstall it.
If these actions do not correct the problem, you might need technical assistance. Contact your software
manufacturer or see "Windows help system" on page 145 for details.
