DNN installation problem

I tried to install the latest DNN 4.8.x last night, but the process is not very smooth. In the middle of the installation, the DNN hung up on the install the database script page. Not sure what was going on. Some people had the same experience (google search). The "Custom" and "Typical" installation choices are not working for some reason. The "Auto" did the job. I think the "Auto" is the traditional way of installing the DNN.
