I need to apply a patch to QGis but installed as standalone instead of OSGeo4w: foolish.

I'd like to uninstall then reinstall via OSGeo4w so as to have linux-like updating support, but before I do so, can anyone advise me whether my maps & WMS info will be saved, or if there's anything one specifically needs to do to avoid extra headaches/work during this process?

Many thanks in advance.


Maps and WMS Info are stored in your user profile, or the registry.

I have QGIS Lisboa standalone and OSGEO4W Master installed in parallel, and both can open the same projects (unless some new or deprecated plugins are installed).

I would not encourage you to relay only on Master, as it gets broken from time to time.

  • Interesting, thanks Andre. So I could just install OSGeo4W now and QGis through that, and use the standalone install if/when the OSgeo4w install breaks? – dez93_2000 Mar 12 '13 at 17:23
  • Hmm... what if I already have OSGeo4W installed and it doesn't work... can I uninstall & reinstall? – dez93_2000 Mar 12 '13 at 17:29

    I use standalone for daily work, and master just for testing new things. If OSGEO4W gets messed up, just delete or rename the root folder, and make a fresh install (or do it on another drive). Older versions of OSGeo4w-setup.exe had a bug, so better use a fresh copy of that too. – AndreJ Mar 12 '13 at 17:54
  • Note that you can install both the stable release and current master from OSGeo4W in parallel without need of any stand-alone installers. – underdark Mar 12 '13 at 20:23
  • interesting. Ok, it feels like a seemingly-buggy OSgeo4W might as well be fully uninstalled w/ qgis (backing everything up) then reinstalling OSgeo4W w/ qgis current master, then installing qgis stable if/when the current master breaks. For reference, I can patch the stable version from the repository right? – dez93_2000 Mar 12 '13 at 20:57
