TheSky will run in Vista 32. It does display a registry error when you start running it under Vista 32 and may have other problems as well. It won’t work at all with Vista 64. It was supplied before 2009 with Celestron scopes.
However, Microsoft did not include the help file needed in Vista to use help on older programs. Please use the following link to see an explanation and instructions on downloading the file you need to run the TheSky's help and tutorial features.
For a version that will run without problems on Vista, please visit bisque.com and see Software Bisque’s TheSky X program. It is also available separately from Celestron as #93700. It has been supplied with Celestron scopes made after 2009.
