4.3.14-95030 (Jul 17, 2014)
Ugh... 4.14 has some sort of issue on win7. Look on the virtualbox forums about deleting a registry key to get it work. I ended up reverting back to 4.12. Otherwise this is great free software.
18.104.22.1680 Beta (Mar 19, 2013)
This beta version scans within archives. It didn't seem to run slower than the release version. Top notch software, the Pro version has real-time support which I don't use.
10.0.92 (Feb 26, 2013)
Failed to install properly on a bootcamped Mac and a desktop HP using an installer. Both machines were completely up-to-date. IE10 would not run. Uninstalled the update and then later tried to install via microsoft update. Same thing on both machines. Uninstalled the update back to IE9. I use other browsers anyway.
1.7.2 Experimental (Jan 22, 2013)
Installed this on OSX and noticed it really chewed through memory, well over 120 megs of RAM. Didn't care so much for the big box status report. It works fine but I reverted back to stable 1.6.16 version.
1.01 (Jan 30, 2012)
The final release of CCleaner hangs on start (LION). Deleted all preference files and re-installed, same thing. Will watch as this develops. The windows version is must-have.
