Yes. In fact I sent them two. The first time I discovered this was in the 5.45 release (the one they recalled) and I sent them a report. I received a reply stating that it had been recalled.
So I waited till the 5.46 release and the command line options mentioned above still don't work. This is the command line I'm using:
/Clean "Z:\Logs\ccleaner.log"
It starts to run, shows the icon in the systray, then quits in about 1/2 second, no messages, no nothing. The last know version that it is working is 5.44.6575 which is what I'm using now.
I did receive a reply to my support request on 9/4 as follows:
