I finally took the latest offer to upgrade to v15 from v13. During the installation I was prompted to also install some registry cleaner that was part of the installation package. As a general rule I never install or use this kind of software and was dismayed that Magix would include it as part of the installation. This is the kind of behavior I would expect from a sketchy download site, not from a company that I just purchased a product from. I don't remember Sony ever distributing any software with their installations that was not directly related to video production.
