I did install in Win 2008 "Bulk Rename Utility (64-bit), version 220.127.116.11 for Windows 7 (64-bit), Vista (64-bit), XP (64-bit), 2003 (64-bit), 2008 (64-bit). Complete with installer." (http://www.bulkrenameutility.co.uk/Downloads/BRU_Setup_WinNTx64.exe), but when trying ran returns "1 item(s) processed, 0 item(s) renamed. 1 item(s) required no name change".
I did this same action in other server win 2003 and works, maybe dont alow or other thing but too cannot see log files.
