Hi, it looks like this file is needed for Hugin to automatically find
control points. I am running Windows 7 x64.
I cannot find a download location for this file, I have looked through
many threads but the links are all broken.
The Hugin SourceForge has a download, but this version is not built.
Can anyone tell me how to build the SourceForge version, or provide a
download link? Without the functionality to automatically find control
points, Hugin does not work for me.

We don't really use autopano-sift-c much nowadays, since the control
point generator that is distributed with hugin (it's called cpfind)
usually does a very good job, and autopano-sift-c uses a patent-
encumbered algorithm. So I recommend you use cpfind unless you have a
very good reason not to.

My very good reason is that it never actually finds anything. :(

Well, nor autopano-sift-c work everytime. That's why I usually mark 2 or 3 control points manually between each image pair. Anyway, I have a version of autopano-sift-c that I use on XP and I can give you it. I'll try to send to your private email.

CPFind worked for one panorama, that was taken with a 100mm lens. So, very little distortion across the images.

But for a panorama I took at 24mm, it couldn't find even a single CP. I just used Carlos' autopano-sift-c with the same set of images, and the outcome was 327 CPs. That is a huge difference, and now I am able to assemble this panorama almost automatically. Thanks for the file Carlos!

This sounds very odd to me. I (like many others) use cpfind on a
regular basis with various lenses and it never fails me. I'd be
curious to have a look at your images for which it couldn't find CPs.
Do you have a way of putting them online somewhere (two are enough) so
I could have a look?

I'd also be curious to know which version of cpfind you use. Cpfind is
quite a recent development, and if you're using an early stage it may
well fail, while a recent version would work. You can find out the
version by calling

cpfind --version

on the command line.

Finally, the result of cpfind depends on the parameters it's called
with. Since you seem keen on finding many CPs, you could try and use
my favourite setting (from the hugin preferences):

--fullscale --sieve2size 5 -o %o %s

Oddly enough, I just tried two of the images and it worked fine. In total the panorama has 75 images, when I load only a couple CPFind seems to work, otherwise I get this output:
