Resets settings to recommended default values for many popular codecs and DirectShow filters. All this information can be very useful for problem solving purposes. It also includes some useful information about your hardware and drivers. This allows you to generate a very detailed list of all the codecs that are installed on your computer.
If you are experiencing a sound problem that affects multiple programs, then the first thing you should try is to re-install your sound driver. There can be many other causes for sound problems, and those are not detected by this tool. This fix is only available when this specific problem is detected. This fix will restore those required Registry keys. If certain Registry keys are missing, sound will not work in most programs. The fourth fix is one for a specific sound related problem. This is helpful if they somehow got removed. The third fix will re-register the base DirectShow filters of Windows. The Codec Tweak Tool can remove the invalid references. Those keys can for example get left behind when a codec is not properly uninstalled. Such invalid references are Registry keys that for example point to non-existing files. This will perform a scan of the Windows Registry looking for invalid references to codecs and filters. The first two fixes detect broken VFW/ACM codecs and DirectShow filters. If you have installed K-Lite CODEC pack, it includes a tool which allows you to tweak features of the playback CODECs, as well as tweak Windows' own playback tools. If a 3rd part CODEC (like K-Lite) is installed on the same computer, Acquire Player by default is designed to revert to use this, which may cause playback issues which are not covered under support.
Note, unless specifically advised by Acquire staff, K-Lite should not be installed on any systems as Acquire includes proprietary playback technology.
