No, no error message. It DOES show up (as many times as I clicked Setup.exe) on the Processes page of the Task Manager. Anyway, after multiple reboots and trying over and over again, it finally loaded. I have no clue what I was doing wrong but it's happy now. And I'm happy with it - I loaded a bunch of my Later folder materials quickly and painlessly - now I just need to move them around to get my folders back under control!
