I try to install OSGeo4W but when I tried to run it appeared an error message about ippj-5.3.dll is missing... does anyone know what happen?

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.
