  • After i?ve tried to export a test project (Home tab -> Export project Button) this error came up every time..

    if i export with (file button / export project) construct crashs sometimes...

    Construct 2 Check failure


    Check failure! This is probably a bug:

    pngcrush.exe did not output a file

    Condition: false

    File: html5.cpp

    Line: 1036

    Function: void __cdecl Exporter::PngCrush(const class std::basic_string<wchar_t,struct std::char_traits<wchar_t>,class std::allocator<wchar_t> > &,const class std::basic_string<wchar_t,struct std::char_traits<wchar_t>,class std::allocator<wchar_t> > &)

    Build: release 52 (64-bit) checked

    Component: HTML5 exporter

    (Last Win32 error: 2)

  • Does the exported project work OK if you ignore this error? I think it might be a false positive, so I'll disable the message for the next build. I'm just preparing the new build now, it should be out in an hour or so.

  • the export seems okay... images sizes are orginalsize (no shrink)..

    so only the error appears..

    btw.. take your time ;)

    the error wont crash c2.. so only the images sizes are affected i think..

    ah another point..

    after i�ve delete a unused sprite the error pop up only sometimes (random).. and the images has their orginal sizes

    and if the export runs successful, the imagesizes are shrinked a bit..

  • r53 is released now, is it any better?

  • Yeah..

    i?ve tried every PNG Compression on the Export Dialog with and without minifying the scrips.. (opened from Home tab and File Menu)

    no error appeared :)
