Good sound, annoying registration

My husband has free programs and those used that came along with his diverse musical toys. The Music Maker is the first purchase software that it uses. Among the free programs he wants to no longer back. He liked the sound quality (for the money ok, you always have to see the purchase price) and the overall design very well. His U-Control Keyboard comes with a little fiddling with the Music Maker.
Here with a Win7 64bit PC with the program is now the first day round, so far no crashes. Let's see if it stays that the next few weeks.

Only the installation is plenty of annoying, hence the deduction of points. Only run the custom installation, otherwise an equal times palmed everything possible (eg the cheap route CCleaner) will. That's a No. The compulsory registration I find unnecessary.

Therefore, for the first four points. Everything is running smoothly so far, there are no crashes or trailer, my husband is very satisfied with the whole program.
