I cannot get Astrotortilla 0.8 x 64 bit to run with BackyardEOS in my Windows 10 x 64 bit laptop environment.

I am have been trying to get Astrotortilla 0.8 x 64 bit to run with BackyardEOS in my Windows 10 x 64 bit laptop with no success.  I have been using Astrotortilla with BackyardEOS successfully in a Windows 7 x 32 bit environment for several years in a much slower older laptop but wish to move to the Windows 10 x 64 format for speed and multitasking advantages.  I have tried the suggestions given below – to download and run AT 0.8 and the latest Cygwin Astrometry but get the error: 1 [main] bash 11404 find_fast_cwd: warning: ”Couldn't find FAST_CWD pointer” when trying to solve a stock image (the same image was quickly solved with my Windows 7 x 32 bit laptop).  The path in the AT configure menu for Cygwin Shell is: C:\cygwin\bin\bash.exe –login -c “%”, but this bash.exe in my copy of cygwin contains nothing!

 Could someone point me to a recent site for AT and Cygwin download that works within the Windows 10 x 64 bit environment?  Or, if this is no longer possible (please see discussion below), what plate solving software has been made available to work with  BackyardEOS within the Windows 10 x 64 bit environment?

I have the same problem...Trying to install AT 0.7 on a new Windows 10 x64 PC. All accesses to http://astrotortilla.kuntsi.com are failing. Going there by typing the URL into the address bar I get a 404 error (page not found). IS THIS A DEAD PRODUCT???

Close to dead, and in two parts.  First off, the old Astrometry.net Cygwin packages were so out of date and full of potential security issues I had to pull them offline. The FAQ on has an alternative way to get it working using the 0.8 test build, and if you're running Windows 10, then the Windows Subsystem for Linux might also serve as a possible part of a better solution that the old cygwin packages.

Second, my trusty old dev setup let out the holy smoke, and the dev tools used to make AT don't work on the newer Windows versions. I did have a plan for AT2 full rewrite, but that has been on hold for many years and "competition" has caught up with easier to use solutions. If I get my astrophoto setup running again in the next few years, I might revisit that idea.

As you can see. AT is no longer supported.

Recent versions of BYE support ASTAP as a plate solving tool.
