But why then, why do seemingly mundane tasks in an installer sometimes take several seconds? Something like "calculating required disk space", why the flipping heck does that need several seconds to complete, when the installer knows very well in advance how big the program is that it's about to install, and getting the remaining free space from the OS takes a literal nanosecond. Or something like "registering components", what? What components, and registering where? And why does it take a full golddarn minute?<br><br>My though process is kind of like this: computers can do billions of things in a second, so if something takes a second, the program/installer is making the computer do billions of things. So then, why? And what?
