Comodo BOClean

I see a new version of BOClean is out (here http://www.majorgeeks.com/Comodo_BOClean_Anti-Malware_d5616.html). I'm running BOClean on my PC. How do I found out which version I have installed? I'm pretty sure it's 4.26 but I'd like to know if it has updated itself, so, does BOClean auto-update itself to newer releases? I remember when I was running v4.25 and v4.26 came out; I got a warning saying that v4.25 would no longer be functional if I didn't uninstall it and install the newer v4.26. Will this happen with v4.27? Should not even think about it and just remove v4.26 and install 4.27?

Thanks.

Finished about an hour ago. Yep, have to uninstall 4.26 before installing 4.27.
