Hi Liann, I will try to help
It sounds like you dont have all of the windows components installed, (.NET framework 4 and C++ runtime).
When you install music manager these components should try to install automatiaclly for you, if they are not installed you might get errors.
Run the music manager install again and give it
plenty of time to install these components...
If you have no luck just let me know and I can give you a remote desktop session tomorrow (sat 8th) to try and fix it remotley for you :-)
