Hey there, you probably have seen this message pop up before, or if you haven't, it pops up when I try installing a program and the installation seems to fail. My computer wasn't like this a few days ago but now whenever I try installing a new program, the message pops up again and it's very annoying. My mum says it's because I installed Google Chrome a few days ago, and her case seems true because the message popped up after i installed the Google Chrome. What's the problem, and how can I fix it?

By the way, I also tried uninstalling Google Chrome after that, but that won't do the trick :\
