  • Hello
    I have used Opera for years (for testing my own sites or visiting others which work differently with SeaMonkey, Internet Explorer etc) and have always been very satisfied.
    I wanted to update and used the installation programme v. 11.10 but it installed Opera 20 'stable' without even asking if I wanted it.
    'Stable'!!! - I tried on two different computers with Windows XP SP3 and both times the installation crashed with a Blue Screen of Death. After a hardware reset the programme seemed to work, but I removed it because I had no confidence and restored the systems.

    What is the latest version of the plain ordinary Opera which works simply like before? (and doesn't install v. 20)

  • Thanks, pesala.
    I tried this (12.17), but it's no better.
    At the end of the installation the program started but the system hung up (no mouse or keyboard, so no <CTRL>-<ALT>-~~: a hard reset necessary.
    Once re-started I tried running the program. It requested an HTTPS access to, port 443 (granted through my firewall); then HTTP to, port 80 (granted); then the same as the first again. At that point it re-started the computer without warning.
    So I have restored the system again and am giving up on Opera.

  • Port 443 is a comsec port for web browsers for http over TLS/SSL (ie: https), that displays the "secure" padlock icon when the link is established. is a Google server. Opera contains Google search engines in both the Old (Presto) Opera versions and the New (Blink) Opera versions, and is the default engine "out-of-the-box" in both version series 12.15-12.17 and 15-22.

    It's possible that a tightly locked-down firewall and/or intentionally blocked Google URLs might interfere with a correct installation process... but it seems peculiar that even that situation would cause a Blue Screen and hang the mouse/keyboard interface.

    What is your active AV and firewall software (as well as any other active anti-malware products), and are you using multiple user accounts? Also, where did you obtain the "installation programme v. 11.10 that caused the initial installation of Opera 20?

  • Hello Blackbird, thanks for the information.

    By the way, I tried Apple Safari and rejected it because it is very difficult (under Windows) to use search engines other than Google, Bing or Yahoo - and I don't (and won't) use any of them.

    Yes, it is strange that blocking certain URL's causes the programme to crash (the dashes in my last message were originally "ctrl-alt-del" (with <-> - I suppose the forum software thought they were HTML).

    My firewall is Sunbelt (Kerio), I only have an anti-virus AVG on one (different) computer in my network for testing purposes (as a professional I don't ever do what one shouldn't and I have never had any virus).
    There are no multiple user accounts on any machine (except 'administrator') and everything is always installed for only the current user.

    After the Opera crashes it was necessary to use ASR to restore as no restauration points worked. So I lost any later history.
    From memory it came from clicking on a link within Opera which led to an archived version page (I downloaded it a while ago).
    I have only ever had the v. 11.10 installation program - it downloaded v. 20 from Internet during the installation without asking. I only realised what had happened when I saw it installed in the Control Panel -> Add/remove programs.


  • What is most peculiar about your problem is that an old Presto Opera version (12.17 or lower) should never auto-update to a Blink Opera version (15 and above). They are different animals entirely, so it's hard to understand how Opera 11.10's installation could have ever installed Opera 20, even if it attempted to invoke its auto-updater. That 11.10 failed to install cleanly (without crashing) on 2 different systems raises questions about possible corruption in your copy of the installation program. Another possibility is that 11.10 itself had some stability "issues" upon installation that were corrected in later versions, and 11.11 did include at least one installer crash fix that I know of. You can obtain various clean Presto Opera installer versions (for Windows) from the Opera archive: and that's the only place that's recommended for obtaining them.

    As far as which "plain ordinary Opera which works simply like before", you're apt to get as many different responses as users. My own preference for an older Presto Opera version would be 11.52; @pesala has stated he prefers 11.64. When I currently run a newer Presto Opera version, I prefer 12.14. None of these (including your 11.10 version) should install v.20, since that is a Blink version that should only be installed upon specific user download from the Opera site or from within an earlier Blink Opera version (15-19) via their own built-in Blink auto-updaters. To reiterate: Presto Opera versions should not auto-update to Blink Opera versions, by design. While that conceivably might change at some future date if Opera specifies it, such a date has not occurred nor been announced.
