x264_64 AVS open error

[Yiu]

Hi, Doom. I'm not new to DVD ripping or conversion at all, but I am having trouble with trying to get x264 to function correctly.
I have this as a cmd:
"C:\x264 BitRate Calculator 3.1\X264\x264_64.exe" --vbv-bufsize 2500 --bitrate 2000 -o "C:\ia3.264" "C:\ICE AGE 3.avs"

and here is my AVS file:
DirectShowSource("D:\Users\Yiu Korochko\Desktop\ICE AGE 3.mp4", fps=25.000, audio=false, convertfps=true)

I am developing a video calculator/converter for x264 and it is nearly completed.
I can get lame to encode the audio of the file yet x264 refuses to work with my AVS file and I get this error:
avs [error]: failed to load avisynth
x264 [error]: could not open input file `C:\ICE AGE 3.avs

I know how to use MeGUI in great depth, but I'd like to finish off my program so that I can convert faster and easier, so any help is appreciated.

*NOTE: I ripped my own Ice Age 3 DVD, I did not obtain the file illegally. It is only used here as an example.*

You know that 64-Bit x264 cannot work with the "normal" 32-Bit Avisynth and that it will require 64-Bit Avisynth ???

Strange I dont have avisynth 64 installed yet MeGUI seems to use x264 x64 fine.
That being said, how am I to use avisnth64 instead of 32 buy default?

Response is very appreciated btw.

*thanks for link

MeGUI pipes filtered content from 32-bit Avisynth to 64-bit x264 using vfw4x264.

MeGUI pipes filtered content from 32-bit Avisynth to 64-bit x264 using vfw4x264.

So is there any benefit to using x264 x64 bit if avisynth is in 32 bits? And how would I implement x264 through vfw4x264? Simply:
"C:\x264 BitRate Calculator 3.1\X264\vfw4x264.exe"
"C:\x264 BitRate Calculator 3.1\X264\x264_64.exe"
--vbv-bufsize 2500 --bitrate 2000 -o "C:\ia3.264" "C:\ICE AGE 3.avs"?
I am new to communicating through all these console apps so excuse me if I'm asking many basic questions...

Or wait a second, would I set the program to vfw4x264 and it will open x264 from the same directory automatically?

32 bit works fine...
other than that im pretty much set.
