MuseHub still won't open

I have tried everything and I actually posted about this a few days ago but nobody got back to me. I can't open the muse hub app and I also can't reinstall it. I have uninstalled it and the installer and whenever I do when I go to reinstall it, the installer stays open for about 2-3 seconds. I switched from MS3 to 4 mainly for muse sounds, however I am having a lot of problems and haven't gotten to hear a single muse sounds note ever since I first downloaded it around the beginning of this month. I don't mean to sound complainy but it just kinda sucks when I can't even use it for the purpose I originally downloaded it for, especially when it's just wasting space on my computer. I am able to open musescore 4 but I can't get muse sounds as I don't have the hub installed.
