Anyway, Julie thought it looked pretty neat, but it seemed pointless to copy the entire application down from the internet all over again, so I checked and it seemed entirely possible to copy the installation folder from one computer to another. And, theoretically, we're both on the same network, we're both running Windows 7, the whole "Homegroup" functionality seemed designed to allow just such a thing.
No such luck. My computer told me I was part of a Homegroup, but wouldn't tell me the password, or let me leave it. I spent 45 minutes googling for support of any kind, and finding all sorts of things that told me that the Homegroup Client Service wasn't starting up, and here's a list of things that might cause it to start working again. None of which did.
So in the end I copied it up to the NAS and back down again. And that worked just fine****. That ^&*^&* for Gigabit ethernet meaning that it only took about twenty minutes!
**You can dodge blows, and hitting monsters from behind does more damage, etc. Also, it just went free-to-play, so I can try it out without spending any cash.
*** Worse than Brainfuck, not quite as bad as Malbolge.
****I tried to just find Julie's machine on the network, and that didn't work either. Although I discovered, just after the copying had finished, that going direct to the UNC path of her machine worked just fine. Oh well, next time...
