Detecting a program is already installed and asking for Uninstall

Is there a Sample Script that works like the NSIS Installer, where it detects that a copy of the program is already installed, and then opens the Prompt window to uninstall the old Installed Version before installing the new version?

Thanks in advance....

The NSIS Installer script is actually an example in the Examples folder. See makensis.nsi for the code, and makensis.ini for the InstallOptions dialogue which asks you to uninstall.
