I agree with HM regarding the dangers of installing this program (or any) with Administrator privileges, especially, when one person already suspected the installer to have an infection.
Regardless, I had a computer that I could try doing exactly what Bill tried (installing with Administrator privileges). I knew I could easily re-image it if installed any suspicious software. I monitored the Program Files folder as before. No new folder was created, the same as before.
The Aurora_Setup.exe file actually creates other programs to do the install. You might be able to see a System Tray notice, depending on what software you use. For example, Total Uninstall will catch the extra setup program and alert the user.
One thing I have noticed is that at the end of the installs, I get a System Tray notice that Windows Updates could not be checked. For some reason the installer is mucking around in places it need not be for what it supposedly does. Working with images is this program’s purpose (to create good HDR versions). There is no need to require Administrator privileges for installation or operation.
It is too bad this software was not better tested before we were offered the chance to test it out. Now, even if they say it is fixed, I will be a little suspicious and extra cautious.
