What is Clistart.exe?

CLIStart.exe is ATI’s Catalyst Control Center Launcher utility. This file is also referred to as StartCCC. ┬áThe process is related to your graphics card, and is necessary if you modify your graphics settings regularly. However, you need two things to be able to do this successfully. You must have a working Internet connection and Microsoft’s .NET framework installed. The file is not required to enable your graphic drivers and settings to function correctly.

File Information

By default the CLIStart.exe file is located in the C:\Program Files\ATI Technologies\ATI.ACE\Core-Static\CLIStart.exe folder. The most common size of the file on Windows XP is 90,112 bytes. You may also find it in 61,440, 98,304, 102,400, 109,052, 713,778, 21,504, 37,353, 14,348, and 37,124 bytes sizes.

The process makes the following registry entries that allow it to load at system startup.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run HKEY_USERS\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Run

CLIStart.exe Problems

The ATI icon or shortcut is put in the System Tray by the CLIStart.exe process when Windows starts. Although this executable runs at Startup, it is not required. You can choose to disable the process from loading startup, especially if the process hogs system resources and bogs down the computer performance. You must also go to the Start > Programs > Startup folder and delete any ATI related entries from it.

However, you must note that the CLIStart.exe is not an error, so there is no need for users to “fix” this.

If you disable CLIStart.exe from loading at system startup, you can manually start it when needed by following the steps listed below:

If you want to start CLIStart manually, you should:

  1. Go to Start.
  2. Proceed to Programs.
  3. Look for ATI Catalyst Control Center.
  4. Click on Advanced.
  5. Select Restart Runtime.

If you see a file with a name similar to CLLIStart.exe located in a different location than the default, and having an unknown file size, be cautious. Malware programs often adopt names similar to legitimate files and processes to avoid detection. If you are suspicious about the processes running on your computer, run an antivirus scan regularly to detect and remove them. You should also check your system for spyware, adware and other forms of malware with a trusted anti-spyware program.

Always delete any entries that your antivirus and anti-spyware programs find. However, be careful as there are occasions when false positives are generated. After deletion, run a registry scan to remove any leftover entries. Regular registry scanning can also prevent and repair almost any error.

Additional Recommendations for Clistart.exe:

Driver Update: Some EXE errors are related to driver problems such as obsolete, outdated or incompatible drivers. A driver update tool is recommended to scan your system for corrupted and outdated drivers and to ensure that all your drivers stay up-to-date.
