The uninstall…
If a user runs uninstall while the program to be uninstalled is running, he is warned and asked if it should be automatically closed. If he chooses “Yes” the uninstaller attempts to close it down. If the uninstaller cannot close it down, the user is told to close it down before continuing. Up to here everything is good. However, if the user then clicks continue without closing down program being uninstalled, the uninstaller runs!
May I suggest that the continue button just repeats the message to close the program until it has been shut down.
