Hello Jurgen,<br> Thanks for your reply. I have gone through all drives, removed all previous qgis, osg and related files, and then reloaded qgis 1.7.0 and it still gives the same error message. <br> I'm wondering if the QtCore4.dll needs to be installed some where in win 7 before qgis is downloaded. Any ideas or suggestions would be of great help.<br> Thanks, J.R.<br> </div></body>
