I notice I get that error when I hit the Ctrl+F5 to start the installation. Then I close the browser window before completing the installation, then start the installation again. The second time, it gives that error and doesn't really start where I left off.
So it sounds like your initial install isn't completing entirely, much like mine from my previous post that no one answers.
Meanwhile, I have uninstalled all toobars, especially considering google thinks they have the right to block popups and things at their whim, and so I'm going to reboot and try it from a clean browser with no toolbars. And if that doesn't work I'll see if I can change my default browser to firefox and try it using that browser instead so that it will complete.
My install gets hung on creation of the database because I can't press the Next button without getting a javascript error. I have the latest dotnetnuke download from yesterday, so I know it's not me using an old version. But I'm hoping getting rid of the toolbars will allow the javascript to work, if not, then I've got to figure how to get beyond that point.
Also, I've tried using their default database as well as my own sql 2000 database remotely and it does start creating the dbf, just seems to sit on that screen forever, and the next button errors on the javascript.
