I will pass on information that the Meade site link is not working. After all the trouble they have had, I am not surprised that a few things don't work yet.
I also found that the AutoStar Suite 5.5 link does not work. I will pass on that one as well.
As I understand things, the AutoStar Suite 5.5 will work with Windows 7, not sure about 8. I don't think it will work with 64 bit versions of Windows.
The AutoStar Updater is supposed to work on Windows 7 and XP, but when they made the upgrade to Windows 7, it quit working on my personal XP machine even though it worked on all the XP machines they could fine in the Meade Office.
