Older ver. difference and download

  • Hello,
    I was trying to download full portable and standalone (= no internet con., no previous ver., no integration in win , USB-like) old Opera installers. (English only and no mail client integrated is OK.)
    As far as I see for Win 98SE-7 that are Opera ver. 12.14, 11.52, 10.63?, 10.11 which as I read in the forum have been more stabile and fast. I thought I should do it from

    It's not urgent but can you please help with answering these questions:
    1. Is something important lost (unneeded bloat?) if .exe instead of .msi installers are used?
    2. Do _int_ ver. differ from _en_ ver. only by more languages added?
    3. What is the difference between _classic_ ver. and _en_ ver.?
    4. Where could I find for download a reliable copy of an installer for Opera 10.11?
    5. What were the important stability and performance differences between ver. 10.11 and 10.63?
    6. And how about important stability and performance differences between ver. 11.52 and 11.64?
    Thanks in advance for sharing your experiences and understanding.

  • 1. Doesn't matter AFAIK
    2. Just more languages
    3. Probably classic is US install only, not international. There used to be with/without Java too.
    4. Old Versions
    5 & 6. Changelogs

  • 1. The .msi installer change made the integration into Windows a bit smoother, supposedly. I never had a problem, but some users reported odd little things when using the .exe installer, including sometimes having odd things happen on an uninstall attempt.
    2. As @Pesala has noted, the int (International) version simply adds more language support. If you're an English speaker, this only matters in being able to accurately render foreign language characters correctly so that they can be properly exported to a translator like Google. With the en version, Opera seems to render non-English characters in some kind of Unicode equivalent that doesn't export well.
    3. Where the choice is offered, the classic version provides the ability to custom-install Opera as a USB/stand-alone installation, and I believe is always a .exe installer.
    4. As @Pesala has linked. It's always better and safer to download from Opera's own site (or from any software maker's own site, for that matter)
    5 & 6. The details between "minor" versions are best determined from the change-logs, as @Pesala has shared... unless, of course, somebody comes by who accurately remembers something about those versions for some reason. Typically with Old Opera, minor-version bumps had to do with altering a feature's performance or adding/deleting some minor feature, and the details of those could sometimes be obscure, so the change-logs are your best bet.

  • Classic is the 98/ME/NT version, it uses the older installer and will not work on Vista/7/8 - and there is no Classic for Opera 12.x. Otherwise the choices are English, International and MSI ... MSI is used in corporate settings when installing to multiple computers. Barring that the English version won't have the non-English dictionaries and localizations, there are no differences once installed between any of the installers.
