  • I've used Opera for ages on my laptop. Today I tried to update it from Version 42. I got this message: Fatal error upon loading installer executable 214:0, 254:0, 214:0, 259:0.

    I uninstalled Opera, then downloaded the installer file for the new version. When I try to open this, I get exactly the same message as above.

    Any help would be much appreciated.

  • I recommend yo to reset your profile Clean profile, then (after test that works) copy needed files form renamed profile.

    Are you the creator of "Browser Backup Pro"? :sherlock:

  • Are you trying with the online or with the offline installer?
