just to confirm, the content installer has an option that asks the user for the location to install the c6pro runtime. in OS X, it's a vise installer that has "easy install" and "uninstall" options. under "easy install", the default location is the applications folder, but it also has a pull-down menu to "select folder", which would be the c6pro folder. as each new runtime is added to the c6pro content browser, it is assigned a name corresponding to the folder in which the new runtime is contained at time of addition.
