Dear Dr Dean
I want to completely uninstall certain sophisticated aircraft and re-install them all over again.
The default in-house MS uninstaller (W7), though apparently removing the add-on, doesn't. Re-installing shows that the pesky details are still there. The problem still remains.
As a simple evidence of this is that on re-installation I am not asked for the registration / keycode of the programme. And there are still bits and pieces floating e.g. in C:users\myname\applicationa datat\roaming\Microsoft\FSX\simobjects\airplanes> name of aircraft and the add-on is still there.
A Google for a solution to the problem produces several uninstall programmes as options. They may be 'safe' but I am scared to run them
What uninstall programme do you use?
