0x6: The handle is invalid.


Recommended Posts

Trying to update CCleaner using the link at bottom right. When I go to click on Update Now, I get the following message.....0x6: The handle is invalid.

Can someone explain why this is happening and hopefully tell me how to fix it?

I'm running V5.67.7763.

'0x6 handle is invalid' is a Windows error code. Something is stopping Windows from fetching/applying the update.
(Windows Updates, such as the monthly Patch Tuesday updates, can sometimes cause 0x6 errors).

Try downloading the 'Slim' installer from here and double clicking it to install the new CCleaner version.
Make sure that your current CCleaner is not running before installing the new one. (Check in Task Manager and if it's running then 'End Task').

Worried about 'Tracking Files'? Worried about why some files come back after cleaning? See this link:

Common solution to "0x6" problems:

  1. Right-click CCleaner > click Properties
  2. Open the Compatibility tab
  3. Check "Run this program as an administrator"
  4. Click Apply > OK
