Hi,
I am using Opera For more than two years now, This opening problem started only two days back, Since Opera is my favourite browser I tried reinstalling, no luck. I reinstalled again after Registry cleaning, it worked for some time again problem started could not open Opera .As a last resort I used Adwcleaner and Opera is working fine now. My OS is Windows 10 32bit
