    In the last few weeks, whenever I try to play a WMV file attached to an email, I get a message telling me "This file does not have a program associated with it for performing this action. Create an association in the Folder Options control panel.", but of the several programs capable of opening this type of file I already have, I have associated VLC Media Player to open it (and I have double-checked that this is still so in Folder Options, and it is). When I save the WMV file to disk, I can play it without problem. I can effortlessly open other types of file (doc, pdf etc) when they are attached to an email without having to save them first. Any ideas?

    Click start>ctrl panel. Open the Folder Options Icon. In the tabbed menue that appears select File Types.
    This generates an alphabetical list of all of the file types used by the software on your machine. Pictures use file types,jpg,gif and bmp.
    Scroll down to the file extension you have a problem with and click it. Just below the list,you will see an entry showing "Details for the extension. "Alongside that entry is a change button. Click it,and you"ll get a list of possible programs that can be used to open the file type.
    Just have to find the program that will open your extension you are having a problem with

    The problem is the email program specifically uses the Open command to play an attached file rather than the default command which is Play. And VLC doesn't create an Open command, so you get the "no program associated" message.
    It's the same issue with PowerPoint files (.pps and .ppt) if you are using the powerpoint viewer rather than MS Office.

    You can either export the Play key from the registry (located here:HKEY_CLASSES_ROOT\VLC.wmv\Shell\Play), change all occurrences of Play to Open, then re-merge it, or create a new entry via Folder Options.

    In Folder Options, find the WMV entry, highlight it, and click Advanced.
    Highlight Play and click Edit
    Copy the entire line under Application used to perform this action:
    It should look like this for default install on the C drive:
    "C:\Program Files\VideoLAN\VLC\vlc.exe" --started-from-file "%1"

    Note the other entries/settings: Usually Use DDE is checked, Application: contains vlc, and Topic: contains System
    Cancel the Edit window
    Click on New...
    In the Action box type Open
    In the Application used to perform this action: box paste the line you copied above.
    Check the Use DDE box if it was checked under Play and fill in the 4 boxes to match the Play entry
    Click OK, then OK, then Close
    You should now be able to play WMV files without having to save them first.

    You'll need to do the above steps (either reg file or Folder Options) for each file type that you want to be able to open directly from your email program, like WMA or MP3

    Uninstalling VLC will remove the Open command, so you may want to export those keys once you've set them up to make adding them back easier.
