We had the same problem, but solved it by installing it first on a different server. After the installation is done, you can copy the whole installation to the server you want to use.
I know this is an older post but I think this info may help someone install osdate faster in the future? It seems if you get a white screen during setup its usually your php version. I had the same problem recently. To fix it I went into my cpanel and changed the php version to 5.3. Install worked like a charm!
