If programs refuse to install, won't appear on your desktop, can't seem to run without freezing, don't load at a decent speed or function properly, or Internet access is unavailable, here's how to troubleshoot:
General issues
Confirm that your PC meets the software's minimum system requirements. If it doesn't, you'll be unable to run the program without upgrading your computer's hardware. Note that PCs which barely meet or just slightly exceed these minimums may run the software more slowly and can be less reliable. Windows 7 and Windows Vista users can reference the Windows Experience Index to quickly gauge their PC's general capabilities.
Check for compatibility with Windows 7 and Windows Vista.
Close open programs and windows that you're not currently using. These can eat up system memory and processing power, slowing your PC or preventing additional software from running. Try running the program again.
Check available hard drive space. Roughly 5 to 10 percent of your hard drive's total storage allotment should be left free to ensure optimum system performance in Windows 7 and Windows Vista, prevent crashes, and keep Windows running at top speed.
Note Use Disk Cleanup to free more space:
Check for program updates and information on frequently encountered issues at the software manufacturer's website. For Microsoft products, you can also load Windows Update for Windows 7, Windows Update for Windows Vista, or visit the Microsoft Download Center. If you install an update, restart your computer, and attempt to run the program again.
Uninstall or delete unwanted programs in Windows 7 or Windows Vista to cut down on clutter and remove any drain on your system's resources.
Disable programs you don't use to in Windows 7 or Windows Vista by preventing them from automatically loading when Windows starts. If you’re running Windows 7, restart your computer, and try the program again.
Defragment your hard drive in Windows 7 or Windows Vista to improve performance.
Scan for viruses and spyware. Windows Defender in Windows 7 and Windows Vista can help detect and prevent threats, along with preventing annoying pop-up notices and unauthorized home network intrusions. You can scan your PC for free.
Reboot your computer and try loading the program again. If it still won't load or work correctly, you may need to uninstall the software and then reinstall it from scratch and reboot again. Advanced users can also try these advanced troubleshooting tricks in Windows 7 and Windows Vista.
Consult Microsoft Help and Support and the Windows Community. If live assistance is required, first contact the software manufacturer's customer support department. For additional assistance, try Microsoft Customer Service and Support.
