Thank you!
It helped - I installed it

Hello,
May be stupid question, but I can not install Opera on my Vista computer.
Two weeks ago I deinstalled Opera and, I hope, deleted all folders with name "Opera" on computer.
Yesterday I wanted to install it again, but setup programm did not run - neither new setup from Opera-site, nor setup from ftp://ftp.opera.com/pub/opera-winxpvista/36.0.2130.75/win/
The problem is: When I click on program file, nothing happens at all - without any message or error.

What can be the reason?
