[Qgis-developer] How to to make auto unisinstall / install / upgrade of Qgis standalone ?

[Bo Victor Thomsen]

Have a look at this article: 
http://www.qgis.nl/2014/04/22/qgis-in-de-klas-onder-windows/?lang=en

It describes how to use the --configpath qualifier to change the 
location of initialisation parameters from the registry to a specific 
directory and the location of plugins.

In short:

 1. Make a standard installation of the new qgis

 2. Make a directory alongside the "bin", "apps" and so on in the
    c:\"program files"\"qgis wien" directory. Call it "inidir"

 3. Edit the c:\"program files"\"qgis wien" \bin\qgis.bat to use the
    --configpath parameter like this:*/
    /
    //*//start "QGIS" /B
    "%OSGEO4W_ROOT%"\bin\qgis-bin.exe//*//--configpath %~dp0..\inidir
    //*//%*//**

    (Second last line in the bat file)*/

    /*
 4. Save the edited qgis.bat as qgis2.bat in same directory as qgis.bat

 5. Start QGIS by doubleclicking on the qgis2.bat file. First time
    around QGIS wil blow up. Next time it will run fine.

You can then "install" the new QGIS by copying the  edited "QGIS wien" 
directory from the original pc to the root of the c-drive on a new pc,  
make a short-cut to qgis2.bat and place it on the desktop

I can't help you with the deinstall of the old qgis.
