I'm thinking a setting to toggle for *.tdes versus *.hyper extracts might not be included. Though then there could still be two options:
(1) As you mentioned, you could install a slightly older version of Logshark. More than likely v2.1 would get you back to *.tde files.
(2) Other option is you could do a side-by-side installation of Tableau Desktop. Because the version number is included in the directory path during installation, you can run two different versions of Tableau Desktop side by side and they won't share any components. So if you installed Tableau Desktop 10.5. or higher that would recognize hyper extracts.
Thanks Mark.. I actually went ahead and downloaded 2.1 and was able to get it set up with our Tableau 10.1 version. I appreciate the response!
