The codec allows you to preview the recording you just took. The recorder itself and the encoder both seem to work just fine, but when I try to preview a recording it says it can't find the codec. The codec is definitely there and in the same directory. The error

The codec in the same directory as everything else

EDIT: I have tried reinstalling. It did not fix the problem. I am having the same problem on 2 other XP machines as well

EDIT: I tried re-registering the codec per Aaron's suggestion. The registration succeeded, but I still get the same error when I attempt to preview a recording

EDIT: After doing some more research, I was able to find a version of MS Expression 4 Encoder "without codecs." Surprisingly, this version works perfectly fine on Windows 7 with no errors, but the exact same installation produces the same errors I have already described when I try to preview recordings in Windows XP. How do I get the program to work as well on XP as it does on 7?

  • What software are you using to preview the video? Cannot tell if it is Expression or something else like VLC. – kobaltz Jul 8 '13 at 16:48
  • It is Expression's previewer. I added pics – Michael Jordan Jul 8 '13 at 16:53

    What happens when you reinstall Expression? It may relink/register the DLL. – kobaltz Jul 8 '13 at 16:57

    You might also try re-registering the codec DLL manually in Command Prompt, via the regsvr32 command; the actual invocation might be something like regsvr32 c:\path\to\codec.dll. – Aaron Miller Jul 8 '13 at 17:29

Try uninstalling the Codec and re-installing it. Get it from this link:
