Hi, can anyone help me with this error im getting, its just a simple picture i want to add to the language select startup box,

i have the necessary paths in my script but still get this error.

i already included in files section

Source: "Files\spl.png"; DestDir: {tmp}; Flags: dontcopy

with all handles and in FMXDesigning i already
state

LangGameSplash.FCreate(LangForm.Handle);
LangGameSplash.SetBounds(5, 5, 266, 89);
LangGameSplash.FillPicture(ExpandConstant('{tmp}\s pl.png'), wmTileStretch);
LangGameSplash.HitTest(False);
