@omov Ahaa i didnt do any magic , im not tech expert too , i just casually visited the link and installed it , just now also i went that link and it says " installed" . may be my configuration is good and no malware or any malcious software , tats why it worked i think. try again after re installing opera ,make sure you downloaded correct version for your pc (x32 or 64) . delete any previous entries , scan your pc for malware or malicious soft . i think you have high configuration pc , mine is low config one , if it works on my pc then you shouldnt have any problem . may be some soft conflicts or some other blocking that ..
