"hostilizes me gratuitously " is a little extreme, but in any event please accept my apology, I am in no way being hostile toward you. And you are correct, your assumption was on another case, not my situation. But also, without any information as to the situation, you assume I am "messing about" and caused this problem myself, and in so doing have treated me with the same lack of reason and logic I did you. You certainly are knowledgeable enough to imagine that a circumstance might arise where one needs to deal with a sub-folder in the Program Files folder. In this case, due to a technical issue with PhotoShop, Adobe recommended an uninstall of the software, and when the uninstall routine failed to remove the program folder, recommended to manually remove it. And that's how I came to deal with the Permission Required issue. And this is solely within the Windows VM. This is a virtual drive within the VM and it is not visible from within OS X. Thus far I have still been unable to resolve this problem, but did get around it by re-installing to another custom folder. Perhaps you have a suggestion.
