@leocg i did runned the installer as admin, i right clicked and clicked "run the installer as admin"

@temminckiiii I AM a administrator, and no i not reinstalled windows.

@temminckiiii i tried that, but when i go to reinstall opera it not let me change from "current users" to "all users" opera is also not showing in the default programs list for windows 7.

I always had Opera as default browser, for some reason someday it asked me if i wanted to put it as default again, i said yes, but even after saying yes, it keep asking me if i want to set it as default everytime i open Opera why is this happening?

@leocg google has a button to reset any extension data don't opera have something like it?

@leocg i checked and there is no reset settings button there.

How can i reset the settings/data of a extension without need to remove it and install it again.
