Problems while running CCleaner

1.    You have set files or folders to be included, but they are not being cleaned.

As well as adding files or folders to the Include section of the Options area, you must also tell CCleaner you want to clean custom files and folders. You can do this in the Cleaner section before you run a Cleaning scan:

  1. In CCleaner, click the Cleaner icon at left.
  2. Under the Windows tab, in the Advanced section, select the Custom Files and Folders check box.

2.    You cannot clean other user accounts on your computer.

CCleaner currently only cleans the current user account. If you want to clean other user accounts, you must log into those accounts and then run CCleaner.

3.    When you try to run CCleaner, you see a warning dialog box from ZoneAlarm firewall.

ZoneAlarm is a common security program. It checks for suspicious program behavior and alerts you if an unknown program starts to ask for access to system files or the Internet.

If you run CCleaner for the first time when you have ZoneAlarm installed on your computer, you may see an alert from ZoneAlarm. You may also see an alert when CCleaner checks for an update. Click Allow in the alert to let CCleaner continue.

To avoid seeing any more alerts from ZoneAlarm about CCleaner, select Apply this setting to all suspicious behaviors exhibited by this application, and then click Allow.

Note: CCleaner contains no spyware or adware.

4.    When you try to run CCleaner in Windows Vista, you see a User Account Control dialog box.

Windows Vista uses the User Account Control (UAC) feature to prevent users from accidentally running spyware or malware or making major changes to how Windows runs (see http://en.wikipedia.org/wiki/User_Account_Control for more information). It does so by asking you to confirm when you are about to run certain programs.

When you start CCleaner, you may receive a UAC warning. Click Continue to use CCleaner.
