Instead I decided I'd pretend to be a sane adult and parked my car and checked if the package was on my doorstep. And it was! So yay, my whole lunch hour to install it!
I put the DVD in and... nothing. Okay, maybe it didn't like the DVD-RW drive, so try the DVD-R drive. Nothing. Ack!
So clever, clever me went into Windows explorer and into the DVD that way. I picked the most likely thing to click on, but I had looked too fast and missed the 'Windows Installer' icon. Heh. But setup.exe seemed to work, too!
The installer took a surprisingly long time (20-ish minutes?), then I got to register and now it's checking 14,000 files. I just hope it will do the download without me having to click 'ok' at any point, because I doubt it'll finish checking before I have to go back to work.
If all goes well, it'll be finished when I arrive home tonight! Eee!
Edit: Woo, checking went fast (about 20 more minutes?), now downloading 257 files. Gotta go back to work soon though. :(
