How to install/uninstall DLL and AX codec/filter files

Last update: 30 May 2004 | 229478 views

1. Unarchive the package and use the files from Release folder if you're running Windows 9x/Me or Release Unicode if you're running Windows 2000/XP.

2. Copy DLL or AX files in system32 folder [ C:WINDOWSsystem32 ]

3. Click on Start > Run...

• To install the files, type: regsvr32 filename.dll or regsvr32 filename.ax
• To uninstall the files, use: regsvr32 -u filename.dll or regsvr32 -u filename.ax

4. In the end, you should receive a message saying that your file was succesfully installed/uninstalled.

An easy way to register/unregister [install/uninstall] the files is to use one of these small tools:
• RadLight Filter Manager - can be used to list all registered codecs and to register or unregister codecs.
• DirectShow Filter Manager: helps to list, sort, find, add or remove DirectShow filters.
• RegShell - a handy utility that will help you avoid the inconvenience of running regsvr32 from the start menu all the time.
• DllRegSvr - allows to register/unregister DLL and OCX codec files using RegSvr32 tool.
• Emsa DLL Register Tool - register dll/ocx filters, codecs... and get extended file informations.

Some of the more common filters

• "iviaudio.ax" - WinDVD Audio Decoder filter.
• "ivivideo.ax" - WinDVD Video Decoder filter.
• "claud.ax" - PowerDVD Audio Decoder filter.
• "clvsd.ax" - PowerDVD Video Decoder filter.
• "DSCinemAudioDecoder.dll" - CineMaster v4 Audio Decoder filter.
• "DSCinemVideoDecoder.dll" - CineMaster v4 Video Decoder filter.

Note: Sometimes you need to specify the fully qualified path name to files (i.e. C:\Program\Files\InterVideo\Common\Bin\IVIAUDIO.AX).

Doesn't work for Windows7. If you all could put in some instructions for installing this into Windows7 that would make my rating for it go up, but as of now I have to rate it as Bad. :(

What if you are using the codecs for a 64-bit player, such as MPC-HC x64? I want to do the above in Windows 7 x64. Don't those codec.ax extension files need to go into the SysWOW64 directory in addition to the system32 folder? In this situation, how would you register/install the 64 bit file? I am trying to get Media Player Classic to play lossless WavPack files using WavPackDSDecoder.ax, which also came with WavPackDSSplitter.ax, although at the moment I can't remember what I would need the splitter for. I just want MPC-Home Cinema to play WavPack .wv extension files, and it keeps saying "cannot render." Since I have the x64 bit version, I am going to try the above, but use the path name to C:\\Windows\\SysWOW64\\WavPackDSDecoder.ax after RUN regsvr32. We'll see if that register/install(s) it for DirectShow x64 players.
