I have an application file (.exe) but I can open it by mp3. in this way, there is nothing!!!!
how program could I use to open it?????
I apologize to you for my bad english
thank you
please answer me!

duh Errrr you've sort of answered your own question. An exe file is an application. You don't open it, you run it. If you double click on the file it should run. If it doesn't then the file is corrupt and there is not much you can do about it.

Before you run it though, be sure that you want to. Which is to say that you know for certain what it is. A virus can be an exe file.

thanks to answer me! I've said "open" because in Italy use it instead of "run"
I don't konw very well english

I wouldn't worry about it, your English is a lot better than my Italian! Although when I visited Florence, my feeble attempts at Italian made a lot of waiters smile.
