I'm setting up DotNetNuke for a project and I got an error trying to install the database.

Installing Database - Version 4.4.0...FAILURE 400 - Thread was being aborted.

I couldn't find any help anywhere.  I think I figured it out though.  I was using the custom installation option and I'd get the error after what I think was about 3 minutes.  I suspect that IIS was terminating the thread because the request had been running too long.

I didn't actually need to change any of the options for the custom installation, so I went back and selected the Auto installation method.  This worked like a champ and I'm moving forward.
