Your web browser will open a page that includes a lot of detailed info about the related binary files, codecs, filters, plug-ins, and services installed on your PC. You might be able to use this info to help troubleshoot problems.
You should only install codecs, filters, or plug-ins from trusted, authorized sources, such as the official website of the codec manufacturer. Be careful when you install codecs that you've found on the Internet, particularly the free codec packs that claim to include codecs from many companies, because these codec packs might include software that can damage your PC. If you've installed any codec packs and are having problems with the Player, we recommend that you remove them.
