Cubase 5 Cannot Be Installed On System With Net Framework Version Smaller Than 1.0 -

The error message is notoriously poorly worded. The installer isn't saying your system has a version smaller than 1.0 (like 0.5). It’s saying: "I can't find .NET Framework 1.0, and I refuse to proceed."

Let’s break down what this error actually means and, more importantly, how to fix it. Cubase 5 was released in 2009. Back then, Windows Vista and Windows XP were the battlefields for producers.
