.dll broken/corrupted



  • I did a fresh reinstall of Qt today and it was working fine.
    Now I reopened Qt after some time and got this error:
    alt text
    And other bad image message but with Qt5Widgets.dll
    Any idea how to fix this problem?

    Hi
    That should not happen. Installation must have gone bad.
    I have seen such strange errors on pc with Avast running while installing but
    it did say stuff during the install.
    Im afraid you must try a re-install.



  • Same error popped up yesterday and that's why I reinstalled Qt, so can't I just fix it by copy pasting a working .dll?
    The problem seems to lie in ExtensionSystem4.dll and Qt5Widgets.dll maybe replacing it will fix it.

    Hi
    It sounds a bit odd.
    Yes if you have the dll some place else, you could copy over. might fix

    I would
    1: completely delete the c:\Qt folder.
    2: Run a disk scan on my disk.
    3: disable any virus scanner
    run the Qt installer again

    It sounds like it first works. Then after some reboots or time, it stops working.
    Unless you have a faulty disk or something else wrong, it should stay working.
