Old post, but ... question gets a bit more complicated. I saw this while searching the website today:
https://www.stardock.com/products/sdcentral/
Great! It's available! But the download link takes me to a page to either create an account, or update my account info. I update my account info, go back to download, and I'm in a viscous circle that seems to have no end. After more searching, I found this:
https://www.stardock.com/products/sdcentral/support.asp
Which seems to imply that Central is available, but it's part of Object Desktop, which is $49.95.
Is this the only method available, or am I just failing at navigating the website?
