If its not your firewall, you might verify that its not an entry in your hosts file blocking access. That could also be the cause.
If you go to the "Let me fix it myself" section in this doc it will tell you how to check the hosts file on the system having the issue versus the Windows default
I’ll try that. I had tried what I had read about doing the trial download, and that got error 100, but I did download Photoshop and Premiere with the direct links, along with Bridge. I am going to try to some more. I do have Acrobat X Pro that I bought last year off the website. I don’t know if that caused any of the problem. I’m on Vista. I did try on my laptop that has never had any professional Adobe products and has Windows 7, and I was able to start AAM over there. Of course, I do most of my work here where I have a 24 inch monitor on this pc.
I wouldn't think that Acrobat X is related, you'll get errors through Adobe Application Manager if you attempt to install it without uninstalling the prior installation first with Acrobat specifically but shouldn't affect the other products.
Might test in a new admin user also.
I'm moving this thread over to our download/installation forum.
