Howto Manually Register/Un-Register Filters & Codecs

DirectShow Filters carry the file extension of .AX. For the most part you will be dealing with only .AX files, but this same process will also work for .DLL files.

Registering A Filter

1. Locate the .AX file in question. Most of the time these are stored in C:\Windows\System32 or in C:\Program Files\\.

2. Goto Start>>Run>>Type regsvr32.exe "C:\Location\of the\ax file\filter.ax“ - Then Hit Enter

3. It should say it succeeded, if not you likely name to change the path so it is correct.

When running regsvr32.exe, put the path to the find in quotes (ex. "C:/Program Files/Nero/Filter.ax") or you must use the old DOS 8 letter file naming or put the full path in quotes. So C:\Program Files = C:\Progra~1 (Note: Progra~1 is 6 letters/numbers long, followed by ~1 to make 8 total.)

Un-Registering A Filter

1. Locate the .AX file in question. Most of the time these are stored in C:\Windows\System32 or in C:\Program Files\\.

2. Goto Start>>Run>>Type regsvr32.exe "C:\Location\of the\ax file\filter.ax“ - Then Hit Enter

3. It should say it succeeded, if not you likely name to change the path so it is correct.
