How to set ffdshow 64bit as defaul x264 decoder?

[xicudiz]

Hi allI'm using window 7 64 bit, avisynth 2.5 32bit and i have just install K-Lite codec Pack 10.0.5 which include both 32 and 64bit version.
But i dont know how to make ffdshow 64bit as default (prefer) x264 decoder. It's allway use FFdshow 32bit as default x264 decoder.
I tried disable all in Media Foudation in Win7DSFilterTwaker tool but no luck. When play x264 (in avi container) via MPCHC, it still using FFDshow 32bit, when open avsscript

DirectShowSource("videopath.avi")

via MPC or open it in aegisub, it still using FFdshow 32bit as video decoder
So anyone please tell me how can i do to make FFDshow 64bit allways is defaul x264 decode.
Thank you.

32 bit software requires 32 bit codecs and filters. 64 bit software requires 64 bit codecs and filters. The two don't mix.

Thank you. You mean i have to using MPCHC 64bit, aegisub 64 bit and avisynth 64bit version?

@jagabo: i got problem when install avisynth 64 bit. I downloaded 64 bit Avisynth 2.5.8 w/multithreading from http://forum.doom9.org/showthread.php?t=162558. Follow instruction in readme.txt. (copy avisynth.dll devil.dll from downloaded folder after unrar to C:\Windows\System32)But when run avisynth64_install.cmd i got error msg: 64-bit windows not detected.I'm pretty sure that my system is win 7 64 bit, have avisynth 2.58 32bit installed and run avisynth64_install.cmd as administrator.
Any advise?

Check if Windows is 64 bit with Start -> Computer (right click) -> Properties. Or from Control Panel select System. Halfway down the page you should see "System Type: 64-bit Operating System".

By the way, I don't really recommend using 64 bit AviSynth. Many filters are only available in 32 bit versions. You'll be limiting what you can do. There's no real speed advantage to 64 bit programs. Just the ability to use more memory (which can be a problem with 32 bit AviSynth and some filters with high def video).

@jagabo: as i said: my system is 64 bit.

Then why did you say this:

I'm pretty sure that my system is win 7 64 bit

I was telling you how you could check for sure.

Yes, i checked like you said. Check in my computer propertise and it show 64 bit operating system

Looking at the CMD file it first checks to see if "HKLM\SOFTWARE\Wow6432Node" exists in the Registry. That should exist on all Win64 systems but the script isn't seeing it for some reason, hence the error message. The test works fine on my 64 bit Win7 computer but maybe it doesn't work in Windows Vista? Maybe "HKLM" needs to be expanded to "HKey_Local_Machine" under Vista?
