Hi,
I finally managed to get a Win 64 bit version of the 2016 release working (following steps given on the Wiki page),. Being brave I then tried the latest repository version (7400). Compiled Ok but CPfind returned zero control points. Autopano - sift -c returned a believable number of points but after optimising (appropriate values reported) both the fast and full preview windows only show the pictures in the 'layout screen' positions.
Back tracking it appears that the last working (Windows) version was 7366
Hope this helps in finding the problem
Brian
