Question: While installing the update for the AFPD I get an error message “unable to overwrite”. What should I do?


Answer:  While using MS-Windows Vista, MS-Windows7 or MS-Windows 8 you may get an error message while installing the  update. Please make sure, that the simulation is closed. Than make a right-click on the updated file (which you should have saved e.g. to the desktop) and choose “run as administrator”. Afterwards the update should install without any errors. If the update has been installed with administrator-rights you may start the simulation in the same way.
