Check failure -> pngcrush did not output a file

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...

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 :)
