You could try the OSGEO4W installer. 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.
