I have heard other reports of this problem, and the solution has been to uninstall+reinstall. Apparently the Windows 10 update is setting weird permissions on the ansvr install folders. Let’s see if Windows 10 updates continue to do this and if so, we can look into finding a way to prevent it or automatically repair it.
I’m confused, there is no way to specify what index files to use when doing the solve in SGP right? So if I have extra ones, that shouldn’t matter? Are you saying I need to get 4202-4207?
Okay, for anyone else having this issue with more recent win10 updates, after you do a complete uninstall, I got it working again by running the setup file as administrator (even though I’m already an admin). Right click, run setup as admin. Seems to have done the trick.
This is definitely a permissions issue in windows 10. After running the stop ansvr.bat and start ansvr.bat it stopped working again. If you modify the shortcut to start ansvr.bat here:
C:\Users\YOURNAME\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Astrometry.net Local Solver
Right click on the shortcut => Properties => Shortcut Tab => Advanced => Check “Run as Administrator”.
