QuickTime 7.4 and later are incompatible with Starry Night 6.2.1 and earlier on Windows Vista and Windows XP. Here are some of the problems that users have reported:
Missing portions of the left-hand tabbed menu
Missing object catalogues from the Options tab -> Deep Space menu
Objects don't show up in searches, e.g. can't find ISS using the Find tab
Objects failing to display in the sky even though images are in the appropriate Sky Data folders
All-Sky Image mosaic does not display or does not show up under Options tab -> Stars menu
Problems with panoramic horizons
Corrupted or shortened filenames in the Favourites menu and under Options tabs
Inability to find ASCOM telescope drivers and plugins
If you suddenly started seeing these problems, QuickTime may have automatically updated itself, or it may have updated as part of an iTunes update. Open your Quicktime player and click Help -> About Quicktime Player on the menu bar to see what version you are running.
If you are experiencing these problems while running any Starry Night version 6.x, please update to version 6.2.3, as the 6.2.3 update contains a fix.
If you have Starry Night 5.8.2 or earlier and are running Quicktime 7.4 or later, please follow these steps to revert to Quicktime 7.3.1.
Make sure Starry Night is installed and updated. Its installer may try to detect and install Quicktime updates automatically, so this step must be done first. If you can't skip the Quicktime detection, just let it run and install what it wants.
After installing and updating Starry Night, uninstall Quicktime by clicking Start/Programs/ and looking for the Quicktime menu. There will be an uninstall icon there. (Don't use the Add/Remove Programs utility in Control Panel, as it appears that that does not completely remove Quicktime. You need to use Quicktime's own uninstaller.)
Where do I get it and how do I install it? If you have a Macintosh, QuickTime is probably already installed on your computer. On Windows, QuickTime is installed at the end of the installation of Starry Night.
Windows Vista and Starry Night New computers do not always come with all of the supporting software required to run advanced programs. We see this problem frequently with new Vista computers. Please see...
