This has happened at least 4 times. I ran the previous version of CCleaner with no problems.
I run Windows vista Home basic, with the user control switched off, windows firewall on, AVG antivirus, spywareguard, spyware blaster and BOclean running in the background. When I start CCleaner no other applications are running.
Here is what windows says about the crash:
