The issue with some printer driver is fixed in the beta version 4.3 you can install from https://sourceforge.net/projects/skychart/files/0-beta/ For CdC there is no difference between win10 and win11, but there can be other difference that prevent the config to be saved. First be sure in the Setup menu "Save configuration on exit" is checked. From the same menu try to click "Save configuration now" , is the configuration restored if you restart the program? saveconfig.png (10,765 bytes) |

Thanks, Patrick. The printer issue and the store settings issue are solved now with the beta version. However, I cannot create any star chart. I have loaded various star catalogs, planets, comets, asteroids etc. and have set display parameters to default, but only get a black screen. I also get error messages when trying to load MPC data manually, see screenshots below. What is the problem?

Very strange, I never see this error. This is because the file sqlite3.dll that manage the database for different data cannot load. I see two possible reason: - a mismatch between 32bit and 64bit installation. - the antivirus silently remove this file. Can you check the directory where you install CdC (C:\Program Files\Ciel\) contain the following files: cat\ data\ doc\ catgen.exe cdcicon.exe libcalceph.dll libcdcwcs.dll libchealpix.dll libcrypto-3-x64.dll libgetdss.dll libplan404.dll libssl-3-x64.dll skychart.exe sqlite3.dll unins000.dat unins000.exe varobs.exe zlib1.dll |

Yes, I see all the files listed, plus the file 'varobs_lpv_bulletin.exe' What I also see is that the country time zone cannot be set in the setup menu (see screenshot), although I see that the timezone info is available in the folder "C:\Program Files\Ciel\data\zoneinfo" Maybe I try to uninstall completely and re-install from scratch. See, whether the problem prevails. Screenshot 2025-07-18 164233.png (115,577 bytes) |

I did a complete re-install. To my surprise, my location and other data were still there, obviously from the previous installation. Furthermore, when installing the base kernel of the solar system database, I get the error message below: Screenshot 2025-07-18 171910.png (7,366 bytes) |

Yes, it is completely broken. it is better to totally uninstall, after uninstall be sure "Program Files\Ciel" directory is removed. Check there is no other install of the program at another location. Also remove the configuration directory : %LOCALAPPDATA%/skychart |
|
|
So the issue is probably a permission problem with the directory %LOCALAPPDATA%/skychart , or C:\Users\marku\AppData\Local\Skychart Delete this directory and try to restart the program. |

I did as you recommended. Now, after re-installation from scratch, everything works fine (at least what I have tested so far). Possible reason for the troubles: When deleting folders I found one that could only be delelted with administrator rights. After deletion the PC seems to have been clean, and installation went smoothly. Thanks a lot for your help, Patrick! |

Thank you for the explanation. This loss of access to some file or directory is typical when trying to run the program as administrator. The new version prohibits it for precisely this reason. |
