It's called Sibelius, it's a really good program, I might even buy the full version.

By the way, yes, it's a great tool. I tried it once, and it has excellent sound and many features, but after using Guitar Pro, it became a bit inconvenient for me, and I'm too lazy to get used to it. So, I'll probably either create something in Guitar Pro or record directly from the guitar to a microphone. And if I don't come up with anything in the next few days, I'll send you something from my old collection.
