Auto Vector 1.0

I tried two pictures. The first - jpg, text and lines (scheme) on a white background. The text turned into a set of unreadable dots, the lines were of different thickness, in the connections of the lines were round dots, they sprawled into something shapeless. Plus, in many places colored areas were formed where there was only a white background. The level of detail and other settings only changed the location of dots, but the resemblance to the original does not add. The second was a gif, a graph with four colors. It was expected to be an easy picture to vectorize. The result was the same: all the lines turned into random sets of dots, the letters of the text became blobs of dots of different sizes. When uninstalling the program, it turned out that Uninstall was missing. When I tried to uninstall using the control panel, the program prompted Feedback (probably feedback for the author), which window immediately froze. After uninstalling there was a directory of the program with some file. I uninstalled it manually. In short, I can not take it seriously, as a toy - I'm not interested.
