I was trying to install Microsoft Visual Studio Express 2012. I could actually install Visual Studio Professional 2012 with my license. But Visual Studio Professional 2012 is not supported in my arcane, ancient, outdated operating system. You see, this dinosaur still lumbers on on the mummified limbs of Windows Vista. An infinitesimally small number of computers are still equipped with this. According to Wikipedia, a completely insignificant 1 in 12 computers uses Vista. Of course, the Microsoft business model depends critically on releasing a buggy new criminally-overhead-intensive operating system every few years to prevent a truly stable OS from ever existing. In order to induce the rubes customers to step into a fresh pile of Microsoft droppings, all new software should be backwards incompatible. I really dislike Microsoft.
