I've been a user of ccPortable for close to 10 years. The most recent version (6.13.10517) appears to have a problem. It installs correctly (from my view), but doesn't run. I even went through an uninstall - reboot - delete the directory - reboot - install process; still doesn't run.
Piriform withdrew the 6.18 update a couple of days after it was released, because it was buggy in several respects, one of which I experienced on my computers: it wouldn't run. 6.17.10746 is stable and continues to work very well.
To those who have none, even a little knowledge of computing seems like wizardry.
