I installed the current PD15 along with the Toolbox and Access. I think decided to see what is involved in removing it. Its a mess. Aside from the obvious stuff in /Library and ~/Library and /Applications there are Privileged helpers, and even an Input Method module that required that I boot into single user mode to pull it out. Come on Parallels - either give us a tool to COMPLETELY remove Parallels stuff or document how and what you are installing and how to get it out. For now, given the nervous security people around me, I plan on not doing anything else with PD15 until I find out more about what's going on. VMware Fusion is a breeze to pull out, VirtualBox gives you an uninstall tool. Surely Parallels could do the same. Unless of course the plan is to prevent removal.
