.application file

I've make a app for a company with 3 PCs in Visual Basic .NET 2005. The program was compiled with ClickOnce setup, so it can get updates through WWW. The setup is basically the .application file, the setup.exe is here just to call the .application file.
Everything is ok in 2 PCs, but in one PC the .application file doesn't install anything. The internet explorer opens it in XML-like format. The .application file is exactly a XML file, but Windows should recognize it and run the setup.
Can someone explain me why this Windows doesn't recognize the .application file? I think I have everything needed to run the setup in this PC, including and older version of my app. What is missing?

What's installed on the two computers that recognize it that's not installed on the one that doesn't?

Al42, thanks for your help!

I am sure I have installed in the 3 computers the .NET Framework 2.0 and 3.0 and Windows Installer 3.1, because it's needed by the app to run. I am not able to see exactly everything is installed in the computers because I am fisically away. I need to go to the company and now I am not going frequently.

I've forgot this thread open...
It's simple: you need to install Internet Explorer 7.
IE7 recognizes .application file as a installer, IE6 or less don't understand what the file is.
