After downloading the Windows 7 install file for Ubuntu One (3.0.2b), I click on the file. It immediately opens two small windows (the console and the ubuntu one installer window) and does nothing else. The console has one line at the top: "(downloads) 1%". I have waited for 30 minutes (while doing other things), but nothing proceeds. Any ideas?
OK, I did get it working. To fix the reported problem, I booted the windows machine in safe mode and it installed fine. When I tried to run it under normal circumstances (normal boot), I got the oft-reported problem of not syncing. I then found an older version of Ubuntu 1 (2.0.3), installed it in safe mode, and now everything is working fine.
Hope this helps someone else out there.
