Continuing today's ragey theme, why the fuck do things require space on the C: drive when I explicitly tell it to install to another drive?

Adobe's Audition music editor is the latest culprit of this stupid and archaic trend. The program requires ~350mb of disk space. During the installation it asks where you want to install it, so I decide to install it on to my 750GB drive I've named Local Data. So you know what it does? It installs about 50mb in to the drive I told it to install in to and the other 300 in to my C. Why? Why even ask me where I want to install it if you're just going to stick it all in C anyway. Fuck you. No wonder I never have any free space on C.
