Hi, Today I upload an updated version 2.76c, it correct the bug when you launch from Vista and also the long time problem with ASTORB update.
It is available from: http://www.stargazing.net/astropc/download.html#upd With Vista there is no more "Failed to set data for " message when you launch the program. The problem is you need admin right to set association of .cdc files with ciel.exe. So do it from the Windows Explorer if you need that. Some time ago the ASTORB file format change to accommodate for numbered asteroid above 100'000. This break reading of this file with CdC but I never apply the change before because a tool was available on the group here to convert the file format. With this new version it is no more necessary to convert the file but beware your old ASTORB file are no more readable from CdC. Patrick
