Should have been right there with those two options, looking basically the same. Though it's possible that something about your machine is messing with the sizing - high DPI on Windows 7 is notorious for that, and there are sure to be other potential causes too. Whenever you get a chance to try it again, a screenshot would be nice if it's not there.

There's also some chatter about maybe hiding the all users install behind the Customize button, since it really doesn't gain anything for most people. Then there'd only be two buttons on the front screen, which will make it less likely to be missed.

Thanks for the log. Looks mostly like issues I'd expect when you don't have write permissions for the install directory. Not sure that we have any precedent for dealing with tests that require admin privileges when installed but not in the source tree?
