; Check if QGIS is already installed on the system and, if yes, what version and binary release;
; depending on that, select the install procedure:

; 1. first installation = if QGIS is not already installed
;    install QGIS asking for the install PATH

; 2. upgrade installation = if an older release of QGIS is already installed
;    call the uninstaller of the currently installed QGIS release
;    if the uninstall procedure succeeded, call the current installer without asking for the install PATH
;    QGIS will be installed in the same PATH of the previous installation

; 3. downgrade installation = if a newer release of QGIS is already installed
;    call the uninstaller of the currently installed QGIS release
;    if the uninstall procedure succeeded, call the current installer without asking for the install PATH
;    QGIS will be installed in the same PATH of the previous installation

; 4. repair installation = if the same release of QGIS is already installed
;    call the uninstaller of the currently installed QGIS release
;    if the uninstall procedure succeeded, call the current installer asking for the install PATH
