Nice necro. This thread is nearly a year old. Anyhow, is there some reason why you are using s3rc and not decrapify (which is also in the s3rc-win.rar)?
Decrapify.exe is a hand-holding program for people too stupid to use s3rc from the command line. There isn't any reason for a script to use it.
Ah, right, thanks. Totally blanked on that before having my coffee.
