Enterprise Manager

I have 2 Window Server machines with the same user defined (same privileges), the first install completes without error, the second attempt generates the following exception -

Executing agent install prereqs...

How can I further troubleshoot missing privileges? Ideally, I'd like to install the software with the same user account.
