    What system are you installing it on? – Mapperz Nov 28 '12 at 20:44
  • How did you install it? Did you choose the express option? Which packages did you try to install btw? – R.K. Nov 29 '12 at 8:20
  • For me this error was originally related to trying to install osgeo4w without "Run as administrator". @R.K.'s answer helped – Jonno Aug 2 '13 at 4:40
  • I have the same problem with an installation on Windows 7 64bits. I used the osgeo4w-setup.exe downloaded 24/08/2013 from hub.qgis.org/(exe has no version info) with "advanced install" option as an administrator and I choosed all packages. I get a missing ippj-5.3.dll when I run QGis (1.8) desktop and browser. I re-installed libjpeg package but the problem does persist. Does someone have an idea? JCP – jcag Aug 29 '13 at 4:14

You can try reinstalling the libjpeg package which will replace the jpeg_osgeo.dll with the non-IPP one. Or you could try removing it.


The solution should be: delete the directory C:\OSGeo4W, start installation again and you should select only the package qgis or qgis-dev, do not click on any other package. Then everything runs as it should
