I've been using CCleaner Pro for years and have never, ever had an issue. This morning, on two different systems, CCleaner unceremoniously closes down mid-way through the "make it better" cycle of the automated health check. It hangs briefly and then just shuts down. Windows 10 up-to-date on both system, and to my knowledge there have been no Windows updates since the last time clean-up ran successfully on both systems. Any ideas? Thx.
