Register 32bit CoreAVC codec on 64bit OS

[xyzxyz]

Hi guys

I'm trying to make a silent install cmd file of CoreAVC 2.0 for both 32/64bit operating systems

here is my batch file:

@echo off

%windir%\REGEDIT.EXE /s "license.reg"

mkdir "%ALLUSERSPROFILE%\Microsoft\Windows\Start Menu\Programs\CoreCodec\CoreAVC Professional Edition"

if %PROCESSOR_ARCHITECTURE%==AMD64 GOTO x64

mkdir "%programfiles%\CoreCodec\CoreAVC Professional Edition"

copy "setup\CoreAVC Professional Edition-uninstall.exe" "%programfiles%\CoreCodec\CoreAVC Professional Edition"

copy "setup\CoreAVCReadme.txt" "%programfiles%\CoreCodec\CoreAVC Professional Edition"

copy "setup\CoreAVCDecoder.ax" "%programfiles%\CoreCodec\CoreAVC Professional Edition"

copy "shortcuts\x86\*.*" "%ALLUSERSPROFILE%\Microsoft\Windows\Start Menu\Programs\CoreCodec\CoreAVC Professional Edition"

%windir%\system32\rundll32.exe "%ProgramFiles%\CoreCodec\CoreAVC Professional Edition\CoreAVCDecoder.ax",DllUnregisterServer

%windir%\system32\rundll32.exe "%ProgramFiles%\CoreCodec\CoreAVC Professional Edition\CoreAVCDecoder.ax",DllRegisterServer

GOTO end

:x64

mkdir "%ProgramFiles(x86)%\CoreCodec\CoreAVC Professional Edition"

copy "setup\CoreAVC Professional Edition-uninstall.exe" "%ProgramFiles(x86)%\CoreCodec\CoreAVC Professional Edition"

copy "setup\CoreAVCReadme.txt" "%ProgramFiles(x86)%\CoreCodec\CoreAVC Professional Edition"

copy "setup\CoreAVCDecoder.ax" "%ProgramFiles(x86)%\CoreCodec\CoreAVC Professional Edition"

copy "setup\CoreAVCDecoder64.ax" "%ProgramFiles(x86)%\CoreCodec\CoreAVC Professional Edition"

copy "shortcuts\x64\*.*" "%ALLUSERSPROFILE%\Microsoft\Windows\Start Menu\Programs\CoreCodec\CoreAVC Professional Edition"

%windir%\system32\rundll32.exe "%ProgramFiles(x86)%\CoreCodec\CoreAVC Professional Edition\CoreAVCDecoder.ax",DllUnregisterServer

%windir%\system32\rundll32.exe "%ProgramFiles(x86)%\CoreCodec\CoreAVC Professional Edition\CoreAVCDecoder.ax",DllRegisterServer

%windir%\system32\rundll32.exe "%ProgramFiles(x86)%\CoreCodec\CoreAVC Professional Edition\CoreAVCDecoder64.ax",DllUnregisterServer

%windir%\system32\rundll32.exe "%ProgramFiles(x86)%\CoreCodec\CoreAVC Professional Edition\CoreAVCDecoder64.ax",DllRegisterServer

:end

Theres no issue with registering the 32bit codec for a 32bit OS nor the 64bit codec for a 64bit OS.

The only issue I'm having is getting the 32bit codec installed in a 64bit Windows 7 (I'm using MPC-HC x86 Under Windows 7 64 so I need the 32bit version of CoreAVC on my system).

I've also tried registering the .ax file with syswow64\rundll32.exe which returns the same error, and with regsvr32 which doesn't return any error but also doesn't seem to register the codec for use with MPC.

Appreciate your help
