emp4demux.ax is not accessible for SYSTEM account.

I'm using emp4demux.ax of the version 0.1.13646.080718.

I have no problem with this filter on Windows XP, 7 (32-bit), 2008 Server (32-bit).

I'm struggling to make it work for Windows 7 64-bit machines.

When i start my player application using the SYSTEM account it is failing with error code 0x80040154. Whereas it is succeeding when i start my app using the Local user account. I had observed the registry entries for emp4demux class registration were created under HKLM\Software\Classes\Wow6432Node\.

I had tried various scenarios like
- Registering the filter from ProgramFiles folder and ProgramFiles (X86) folder. - no luck
- Manually creating the registry entries under HKLM\Software\Classes\CLSID\. - no luck

Please suggest me the best way to use the emp4demux.ax filter for 64-bit mahcines.

Thanks in Advance
