Wow. 35 minutes? That's crazy. Did the .NET install fail then? You can tell if it thinks it is installed in the add/remove programs in the control panel.

DaVinci won't install if the .NET failed (since it installs afterwards and uses it). Usually you'd get an error but I guess if the .NET install totally locked up you might not. Not sure why your .NET install failed - obviously Microsoft has tested it fairly extensively and it should have worked for you.

Is there anything weird about your machine? Is it very old?

If you care to try again, I can send you a pointer to the Microsoft site to install .NET from there...but I understand if you just don't want to bother at this point...
