[Solved]Opera fail to start after window fail to boot

  • Not sure if there was an autoupdate yesterday, Opera was working yesterday. When I switch on my PC today, Windows fail to boot, so I reboot and it start in diagnostic mode and recommend autofix, which I accepted. Then Windows boot as normal. But when I try to start Opera, nothing happens.
    Can't find any user profile directory, all I found is user cache and Opera executables. Upon examining the executable directory, there are 5 versions:
    71.0.3770.271 which is empty
    71.0.3770.284 with opera.exe and dlls
    72.0.3815.186 with opera.exe and dlls, debug.log last modified this morning with last line: [1206/091145.323:ERROR:icu_util.cc(247)] Couldn't mmap icu data file
    72.0.3815.320 with no .exe file but has some .pak files, debug.log last modified 1st Dec with last line: [1201/100920.958:ERROR:directory_reader_win.cc(43)] FindFirstFile: The system cannot find the path specified. (0x3)
    72.0.3815.400: with no .exe file, but has some .pak files, debug.log last modified yesterday with the same error message as above
    I suspect there was an autoupdate yesterday and caused Windows failed to boot this morning. Is there anyway for me to get Opera working without losing my stored preferences and passwords?

  • You can uninstall Opera, delete the program files folder, and reinstall Opera. Just don't choose to delete your data when uninstalling. Then, when Opera starts up, it should work jus fine *if* your Opera profile is still where it's supposed to be and not corrupted.

    Your data should be at "C:\Users\yourusername\AppData\Roaming\Opera Software\Opera Stable". If it's not, I assume it got corrupted or deleted when the Windows fix was applied (depending on what exactly it detected and fixed).

    If you profile folder is missing, look under "C:\Users" in Windows Explorer to see if you have something like "yourusername2" or "yourusername.fixed" or something like that where you're now using that new, migrated Windows account profile because of some corruption and Windows automated fixes.

    I would run https://crystalmark.info/en/software/crystaldiskinfo/ to check the status of your drive. It might be failing.

    I'd also load up a command prompt in administrator mode, run chkdsk /r, tell it to scan after a restart and scan your drive for errors (will take a while).

    I'd also make sure your system files are all good. https://support.microsoft.com/en-us/help/929833/use-the-system-file-checker-tool-to-repair-missing-or-corrupted-system.

  • Thanks, I install Opera for USB and overwrite every subdir under new profile with old profile and it seems to work now.
