Did I get an incorrect zip somehow?
No. Have a look at "http://forum.fontlab.com/index.php?topic=9060.0".
Unfortunately Adobe provides the latest version only. I would like to have build 62690, but I cannot download it anymore. This is very annoying, because you have no access to a build, that works, and it makes it more difficult to precisely report bugs. Adobe should keep all versions, that are listed in the release notes, on the servers.
