JohnB256 is barking up the right tree but doesn't quite have it...

It is when Aurora attempts to write to its own directory (configuration files, log files, etc.) that UAC complains.  The current MS approved notation for such data is supposed to be kept in "C:\Documents and Settings\Username\Application Data\Vendor Name\Program Name\".  Aurora doesn't do this and instead just stores them in the same directory as the exe (we chose to do it this way to make tech support easier before we knew about the UAC issue).  UAC doesn't like it.  It is a very poor/weak security that UAC uses though... I've heard (but havent tried it) that if the program is installed somewhere outside the Program Files heirachy (e.g. "C:\Aurora") then UAC doesn't even do this check at all.

What's the biggest annoyance for Windows Vista users? Hands-down, it's User Account Control (UAC), which nags at you to enter a password or click OK every time you make certain changes or perform certain actions. You can turn UAC off in Vista if you'd like, but that leaves you vulnerable. So you might like to turn it on sometimes and off other times.

This program solves the problem neatly. It lets you quickly and easily turn UAC on and off. Better yet, it lets you put UAC into "quiet mode," which in essence turns off UAC for administrators, but keeps it on for everyone else. The program is free, and fixes a big-time Vista annoyance. What else could you ask for?
