Well I never did get a response from CA but I was able to locate my key and get into my account. When I tried to re-download the product it said my download time had expired. Well, no worries, I have them backed up in my Downloads folder, of course.
I tried to install the first file I found and it said "operating system not supported." Then I saw a more recent file and tried that and it said "operating system not supported." Finally I find a third download and this one asked me if I wanted to install in compatibility mode. Aha! I thought I hit the jackpot. So I went to install it in compatibility mode and, you guessed it, "operating system not supported."
BUT on this third try, I did get an additional
dialogue box which said "you're running a 64-bit version of Vista...click here to go to our Vista 64-bit download center for your free upgrade." Awesome, right? So I go there, download the file, and go to install it and I get "operating system not supported."
It turns out that the Vista 64-bit app is not compatible with Windows 7. Wonderful. So my lifetime subscription is no good. On top of that, the products they DO offer have changed. They don't even have a firewall anymore. They only have 3 products: Antivirus with Antispyware (which I don't need), a PC Cleaning bunch of crap, and a Security Suite which is the only product that does have a firewall, plus Antivirus, Antispyware, and crap I don't need.
So even if I wanted to pay for a Windows 7-compatible version of the software it doesn't even exist.
So that issue is resolved -- but the result is that I no longer can use the product after all.
