I am using Vista OS. I am not quite sure if the permissions are correctly set by the installer. The error log file could not be created until I ran the program as administrator. More importantly I did get this error in the log file when trying to do Bible compare, Keyword only. Nothing appeared to be happening, but when I exited BA, I was directed to a log file, I could not find it at first, because it had not been made. Then I thought I would change the permissions to run as admin, and repeated the process that caused the error. This time the file was created as you can see below.
Hope this info helps you trace the problem.
