Marek, this is my mistake... I mentioned in the install instructions that on Windows the Visual C++ runtime components have to be installed, but then I neglected to include them in the download archive. Oops! I've submitted a new Windows download to our web team and as soon as they get it posted I'll let you know and you can re-download. My apologies for the mixup.
Schnerger, good catch! These Labs XTs don't go through the same quality assurance testing as our shipping XTs. You're right, the permissions on Image Export are a little wonky. I've also fixed that and we'll replace the download probably tomorrow. I'll update when it's official. Thanks for the feedback!
