After a hiatus from Windows in March, here is the latest hugin installer. Before heading to the download page, be aware that it still has bugs, some of them recently discovered. There are workarounds too:
For this bug, go into the images tab, select the images for which you need control points and click on the button to generate.
For this bug, just click inside the panorama preview to move the panorama slightly and then go back to the optimizer and click optimize.
Hugin is becoming better, now with a wide variety of control point generators!
