Thanks @mrjj .
The Problem was the Quazip that was linking to dynamic Qt libs witch Dependency walker won't show up at run time.
First i should build it as static like so :TEMPLATE = lib CONFIG += qt warn_on QT -= gui DEFINES += QUAZIP_BUILD CONFIG += staticlib CONFIG(staticlib): DEFINES += QUAZIP_STATIC include(quazip.pri)
Then i should link that in my .pro :. . . LIBS += -L$$PWD/quazip/ -lquazip INCLUDEPATH += $$PWD/quazip PRE_TARGETDEPS += $$PWD/quazip/quazip.lib DEFINES += QUAZIP_STATIC . . .
