I can legally install Sonar on multiple machines as long as I am the only one using it and as long as I don't using it on multiple machines at the same time. I have X3 installed on 2 partitions on one computer - one is dedicated to audio only, an done is more general purpose and used along with Sony Vegas and other toys - works fine.
I am going to be traveling around a bit, so I put Sonar on my Laptop - no issues until I went to install addictive. It allows itself to be installed on 2 computers simultaneously only, and sees the two partitions as separate machines. I must admit I don't think it is correct to add things to a package with a different license to the core product.
Thoughts welcome.
Cheers
