admin1, JudyKay Thanks fo reply. Of course, my current locale is Russia (sorry 4 my english:). When i try to build EXE from picture seqence what contain russian filenames, PTE show error message and hang's up (screenshot in 1-st attachment). In Preview mode all pictures with cyrillic symbols substituted by PTE generated slide with "Image_not found:" message(screenshot in 2-d attachment), latin-named pictures are represented in Preview Mode correctly. I think it's a trial version limitation or bug.
