I have downloaded torbrowser-install-4.5.1_en-US.exe on my Windows XP based computer and when I double-click on it nothing happens. No error messages, no window, nothing... I have already installed torbrowser previous releases (I'm currently using v4.0.8) but I have never encoutered such problem. I have also tried another package (torbrowser-install-4.5.1_fr.exe) but with the same effects.
So if someone could help me, it would be kind.
