Error Code when trying to use a .vbs

Got this error when running "Leatrix latency fix".What does this error mean? How do I fix it? Running windows 7 64-bit

probably the code has an error. You can apply the fix yourself by running regedit and navigating to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\Find the subkey for your network adaptor (hint, look at the IP addresses). and create (if it doesnt already exist, otherwise edit it) a dword entry named 'TcpAckFrequency' (case sensitive) with a value of '1'

But the FAQ at the website says"Why make a script, why not just make a registry file?
Because the keys which are modified are unique to the computer you're using, so it's not possible to make a static registry file and expect it to work for everyone."Sounds like it'd be better to just use a script.

the only unique bit is the subkey for your network adaptor, which I have already covered.

Okay, added it, and restarted. Works fine. Thanks.
