Windows 7 Codec Pack (XP, 2007, Vista) …


  1. thank you so much! i tried everything but it didn't work then i figured it wasn't for windows 7. i searched so many videos and then i finally found yours! i installed and did everything in the video and when i opened it, IT WORKED!!! thank you soo much!! and im gonna subscribe too 🙂

  2. I am re-evaluating this video – I originally used the 3.4.0 version of Windows 7 codecs for MM etc., which is great but have seen complaints from others re: later versions specially the one currenlty on the downloadcnet site. Seems its loaded with ugly stuff you don't want on your computer. If your used to hitting the custom install or advance install then you'll probably be fine if not best to avoid it I think.

  3. hey dude a little prob here. uhm I still havent tried it yet, but i think its better to ask first before everything else… i dont have an internet connection at home. will it work if I download the installer from a different pc and then put it in flash drive and install it at home? pls help tnx.

  4. You may need to convert your video files to wmv format – they may be avi which is not supported by windowsmoviemker. Also you might try downloading Free Youtube Downloader v. from download dot cnet dot com, navigate to the files on your computer and try converting one to wmv see if that solves.

  5. Uninstall and reinstall and dont be so trigger happy. You checked boxes you shouldn't have when installing – see my vid. Windows moviemaker does not support avi files if thats what your trying to edit you'.. need to convert avi to wmv file look online for safe converters.
