How do I play WMV attachments

The most likely fix would be to use a current WMV player for Mac.
MS does not make one anymore; so the best option may be to
get and use one from Telestream called Flip4Mac WMV. I saw
another place where one could get a plugin, assuming for use
with a browser. The following is the main overview...

{For Intel Mac users with BootCamp installations of
Windows XP, etc, the use of Microsoft's player is
still the main option for handling WMV content...}

Good luck & happy computing! 🙂

I use the FLIP4MAC app... works great. I forgot how much I paid for it but it wasn't much.
