I tried uninstalling and installing again using the stand alone installer. This gave the same error so I uninstalled it.
Then I tried the OSGEO4W installer but it did not install exactly where I asked it to, instead it made its own directory on Y (Y:\osgeo_download). It did start up once but after that it failed to start and instead gave the same error about missing .dll's even though they were present. I think I had a problem similar to this several qgis versions ago but it was then resolved, now the issue seems to be back. This is the \QGIS 2.18\bin\qgis.bat file: @echo off call "%~dp0\o4w_env.bat" @echo off path %OSGEO4W_ROOT%\apps\qgis\bin;%PATH% set QGIS_PREFIX_PATH=%OSGEO4W_ROOT:\=/%/apps/qgis set GDAL_FILENAME_IS_UTF8=YES rem Set VSI cache to be used as buffer, see #6448 set VSI_CACHE=TRUE set VSI_CACHE_SIZE=1000000 set QT_PLUGIN_PATH=%OSGEO4W_ROOT%\apps\qgis\qtplugins;%OSGEO4W_ROOT%\apps\qt4\plugins start "QGIS" /B "%OSGEO4W_ROOT%"\bin\qgis-bin.exe %* and this is the directory where the relevant .dll's are Y:\osgeo_download\apps\qgis\bin but it says they are missing even though they are present in this directory. ________________________________ From: Qgis-user <[email protected]> on behalf of Andre Joost <[email protected]> Sent: 26 February 2017 16:23:38 To: [email protected] Subject: Re: [Qgis-user] qgis 2.18.3 not installing on win 10 Am 25.02.2017 um 21:58 schrieb Michael.Dodd: > Have been using qgis for years.

It lets you choose the root directory where everything is installed to. Or have a look at \QGIS 2.18\bin\qgis.bat and o4w_env.bat. The variable OSGEO4W_ROOT might be set wrongly. You get it when you type set inside the OSGEO4W Shell. Override the definition if necessary.
