Did you just received a cli.exe application error? If yes, then your Catalyst software bundled with your ATI Graphics card may be causing the problem.
If you still have the srivers and applications CD, You can uninstall the Catalyst application and reinstall it again. You can also download the latest software version from ATI website. Just make sure you complete the installation to avoid further errors. Next you need to update your ATI graphics card drivers. When you download new drivers, make sure they match your device type or model. If you are still having the problem, it is possible that you have a malware or virus that is causing the cli.exe application error. As most malware does, they dwell in the registry system, altering codes and entries to hide themselves from detection. Run your updated anti-virus and registry cleaner/fixer to fix the problem.
