Sharepoint 2007 Install

I am trying to run rsSharepoint_x64.msi on my sharepoint 2007 server that works with a sql2008r2 instance on another box. I am logged in the the account I used as the Sharepoing setup account.  This account is in the local administrators group. The account also had dbcreater and securityadmin roles in sql, I now added sysadmin. The install terminates with this error in the event logs

Insufficient SQL database permissions for user '' in database 'SharePoint_Config' on SQL Server instance 'fcm-hvsrv2012-0'. Additional error information from SQL Server is included below.

followed by a whole series of similar errors:

What account is this install trying to use?  What would cause this error?
