    <p>Hi,</p>
    <p>I'm trying to install QGIS using OSGeo4W on a new Windows 10
      computer. I've tried several options. I started with the "express
      desktop install".<br>
    </p>
    <p>The installation runs smoothly.</p>
    <p>After installation, the splash screen appear and goes until the
      message: QGIS is ready! But then, nothing happens. If I run QGIS
      with Administrator privileges, it works.</p>
    <p>I've also tried to install with "custom install", just for the
      current user. But using this option, I get install errors
      (complaining about a missing gdal301.dll).</p>
    <p>What can I do (change some permissions?) to have QGIS running
      with administrator privileges? <br>
    </p>
    <p>Disclaimer: I'm not a Windows expert. I probably missed something
      obviously. I've disabled the antivirus software, just in case.<br>
    </p>
    <p>Thanks,</p>
    <p>Jorge<br>
    </p>
