It happened a week ago and I haven't found a solution. I tried searching here and some other sites for a solution but nothing helped. Basically, when I click the wmplayer exe (both x86 and x64) it just does nothing. If I try playing an associated video/audio file it says: "Server execution failed". What I have, basically, already tried: 1. sfc /scannow, 2. Adding admin rights to the services (already had), 3. Tried unchecking and rechecking the "feature" of media player, 4. Tried system restore, but for some weird reason I have only restorations available from the last few days, 5, Tried opening the wm_setup exe but it says that the latest version is already installed and I'll need setup verion 7600.0.7000.7000 to reinstall it (what...?). I would be happy with any suggestions you give me before I end up formatting. Thanks.
