Hey,

I would like to install Music Maker Jam, but it didn't install correctly. It kept saying installing but never actually would install and won't open. I tried reinstalling it but that didn't help. I removed it from the start menu but I have a problem. I can't reinstall it because the shop already says I own the app. I can't uninstall it because it's not in my app list.

Can someone pleases help?

Most of these failures are do to corrupted installs. Try to Custom Install with a new download and burn to DVD
