I was reinstalling Paint.net today, and when I went through the agreements, process of the download, I saw a error message showing this.
Picture (Click me), and when I was going to check the log through the application this is what I got. the installation source for this product is not available. verify that the source exists and that you can access it. I would like to get this problem fixed because I want to make more pixel art on this, I find it the best for it.
