Cannot Download By Using The BITS

I used NClauncher to download a game but when I started to download I encounter an error and got this message.

"The server does not support the necessary HTTP protocol. Background Intelligent Transfer Service (BITS) requires that the server support the Range protocol header." I try many about turn off firewall or antivirus but it doesn't work.

[URL] I try to use method 1 to solve the problem but when I type the command and enter it show message "Windows cannot find 'C:program' make sure you typed the name correctly and try again.. "

then I go look for osql.exe or ExecuteSQL.exe in my computer but they not be found. I think I dont even have them install in my computer and I dont even know what is WSUS and what version do I use.
