 hi,

 Replying to [ticket:1080 martinl]:
 > It would be useful to improve Windows native installer by adding
 '''reinstall''' method. Currently already installed GRASS is removed
 (including user settings) and afterwards installed the new version. It
 would be nice to add "reinstall" option when only modified (size-based or
 marked) files would be replaced. The user configuration should be
 untouched which is the key point.

 actual the wingrass-installer does following
 (see
 http://trac.osgeo.org/grass/browser/grass/branches/releasebranch_6_4/mswindows/
 GRASS-Installer.nsi#L160)

 {{{
         ;.onInit Function (called when the installer is nearly finished
 initializing)

         ;Check if GRASS 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 GRASS is not already installed
         ;install GRASS asking for the install PATH

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

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

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

 so asked is rather an upgrade/update of the installation with a newer
 version '''and''' keeping the user configuration than a reinstall of
 several changed/newer files?

 just replacing modified files (size-based or marked) could maybe
 problematic, if for example the underlying build system has changed with
 newer version of the dependecies?

 best regards
 Helmut
