Problem with installing R12 with Win 2008 (Rapidwiz 12.1.1.9)

Question

I could really use someones help.
I did a download recently of Oracle Financials R12 for windows (I'm using WIN 2008 server) which contained version 12.1.1.9 Rapidwiz. I was unable to get it to work as individual DVD's which is fine, I build the staging area and had better results.
The first error I encountered was the release contained JRE 1.6 but the install referenced 1.5. I took a suggestion that I saw to copy the directory and rename it which worked just fine.
The next error I encountered came during the database install. There was some problem with the database service. It sounds similar to a problem discussed about just the database not related to Oracle Financials but the "fix" to just start the database doesn't seem to apply.
Below is the Rapidwiz log. The warning first mentioned is to check to be sure that the Administrator user being used in the install belongs to the administrator user group which of course it does.
I've brought to the top of the log, the error that I think is occurring. Please help me install, I'm trying to evaluate the software but having trouble with just the install is concerning.

Thanks for the starting point.
The user I am using for the install is Administrator and I confirmed using the NET command that Administrator is a member of the Administrators group and the Domain user group.
Result of NET USER ADMINISTRATOR:

I see that there is a version of Rapidwiz beyond my 12.1.1.9, is this required to get around this?
Is there another cause of this error?
Am I understanding the assignments to administrator correctly?
