What is the size of your downloaded installer? ADE_2.0_Installer.exe is 5,755KB.
Nothing happens if you double-click it?
Double-clicking, right click and selecting "open", nothing. I finally tried following the download tricks for Windows Vista and was able to get it to download. For some reason it comes in blocked. I had to save it to a folder, go to the folder and right click on the file, select "properties" and check "unblock" and "apply". Then I was finally able to get it to run after right clicking again and selecting "open". Thanks for your assistance.
There are some oddities with ADE 2.0 and XP, especially if it is not XP SP3.
Try the older version v 1.7.2 of ADE.
Version 1.7.2, it is a little difficult to find, available on Adobe site for Windows and for Mac.
