Ares Installation Error; error 1072

i started off with ares v. 1.9.1 and downloaded v. 2.0.9. i installed that latest verison but it wasnt connecting ot the internet so i uninstalled it and re-installed the old version. however, near the end of installation, i received this error:

Service " Ares Chatroom server" failed to install with error: System error. Code: 1072.
The specified service has been marked for deletion

i pressed OK, and the installation finished but now Ares will not open at all. i tried many times but nothing. i tried uninstalling and re-installing many times and it still wouldnt open. i googled the error code 1072 and found nothing relevant at all. what can i do to resolve this issue??
