Adobe digital editions - Install okay but doesn't want to open?

Hi, I downloaded ADE on my computer, the installation is okay, but when i try to open it, a window opens saying something like (my message is in french) : "Adobe Digital editions 4.0 encountered a probleme and must close. Please let Microsoft know". And then i clicked on "send the errors' message".

I tried to install it via Chrome, explorer, mozilla, same thing.

I bought an ebook on the chapitre.com's website and can't open it without ADE.

Could anyone help me?

Thanks!
