Something went wrong? Error message

To help our support team investigate further, can you please provide us with the log file that is created when running CCleaner in debug mode?

Run CCleaner in debug mode in 4 steps:

  1. From the Windows desktop, click Start (in Windows 7) or right-click Start (in newer versions of Windows), then click Run.
  2. In the Run dialog box, type <path to CCleaner> /debug. Typically, this will be:
    "C:\Program Files\CCleaner\CCleaner.exe" /debug
  3. Click OK. CCleaner starts in debug mode. You will see the word  [debug] next to the version number at the top of the program window.
  4. Please replicate the issue you are experiencing then quit CCleaner, and use Windows Explorer to navigate to the installation path (the same path you typed in Step 2). The log file will be in this folder in the format: CCleaner_log[date].txt.

Additionally please send the service log file that can be found in the C:\Program Files\CCleaner\LOG folder and it will be named in the format of "ccleaner-service-log-[date]-[time].log"


Please send these files to support@ccleaner.com
