You should probably reconsider having your program require administrator
privileges just to write the log to the C: drive.
Perhaps a sub directory on the C: drive should be good enough? Or the
application's own directory?
Also, if your program generates a lot of logs you should probably write
them to a different drive to prevent it from filling all the space on the
C: drive.
Or make sure you have some sort of an automatic way to delete old logs like
a scheduled task independent of your program.
