You will only see the "Launch App" button for the 1st time. Muse is already insalled on you machine. So, you can go to /Applications(for MAC) or Start->All Programs(For Windows) and look for Muse and launch it.
If you want you can create a shortcut or alias as well.
i'm having the same problem. i subscribed to Muse. i downloaded the App manager and downloaded Muse within that app.
tried to Launch App but nothing happened. it says Muse has downloaded but i cannot find it ANYWHERE on my mac?
sorry, but it is NOT in my applications folder (mac) is there any way i can download it again WITHOUT the App manager as it keeps saying it is installed and it is NOT! i have searched the whole computer for it.
when i try to uninstall via the trial installer (replace or uninstall option) it gets halfway through and an error appears. let's get this sorted please!
