Michael,

Here's the error I got when using: Setting-up the Environment(without IIS). I followed the instructions exactly. Note the:
00: -   Error: Object reference not set to an instance of an object.
00: -   Portal failed to install:Error!

Do you have any thoughts about what to do?

Object reference not set to an instance of an object.

I ran it in auto mode. The only error was the one show in the scripting on the previous reply.
