When I click the download link for Edge Animate on creative cloud apps page, Adobe Apps Manager opens. But edge is not listed as an installable option. The manager only lists 15 possible apps, none of them the edge tools. But all of them are listed on my apps page in creative cloud. Why is this? How can I download and install Edge tools? I am running Vista 64 bit.
Mylenium is correct that Windows Vista is not supported on Windows Vista. This would also be why it is not listed in your Adobe Application Manager. You will only be able to install applications on your computer where you meet or exceed the system requirements.
You can find the system requirements at http://html.adobe.com/edge/animate/tech-specs.html.
