Thank you much! Nailed it with the manual download since CCleaner wasn't up enough for auto-update to work!

That does sound like it would do it. I had the same problem on a Win7 PC with that release and it seemed to clear up and when I looked, the .89 version was just installed per Control Panel (but I knew it had been installed many days before). Any best way to download and install the 2nd version of .89? Would the download page of the "trial" version give me the 2nd rev (then of course need to find that license key)?

Running a registered version of CCleaner Professional on 64-Bit Windows-10 and ever since the last auto-update to v5.89, everytime I run CCleaner the popup box appears for a fraction of a second and then, closes. It also disappears (assuming closing) from the task-bar after I run it. Is anybody else running into this and any thoughts on how to clear it up, hoping it might clear-up after the next update, but not sure when that will happen. Thanks much!
