I am trying to download Photoshop CS5 from the Adobe site. This downloads a file called AdobeDownloadAssistant.exe. When attempting to execute this file, however, Windows 7 tells me that this software cannot be executed. My Windows is not in English so I don't know what the exact message in the English version would be, but translated directly it looks something like this:

Software from this editor cannot be executed on the system. Unblock this editor to execute this software. 

I have UAC disabled, so I am not really sure where this is. The Windows help is not helping either.

    If you right-click on the file and select properties - Is there an option to unblock? It's part of the UAC stuff I think just because it could 'potentially' be malicious.

    The Unblock "feature" is far more irritating with zip files if you forget to Unblock before you unzip the file. Then you have to manually unblock each file individually. It's a pain in the rear.
