Error message

When I try and update CCCleaner I get an error message;

ox6: The handle is invalid

My license is up to date

'0x6: The handle is invalid' is a Windows error code, something is stopping Windows from fetching/applying the update.

It is more prone to happen following a Windows update, and is occasionally seen when updating CCleaner (or any other app).

Try one (or both) of the two suggestions given here:
