Very strange.. Try to install with double click on the .deb file (without terminal). I always installed with double click and don't see any problem... In version 6.2 and 6.3 I changed way of transferring the 2 pdf files to /home/user/MyDocs/Documents but i don't see any problem for this.. I don't know why you have problem with this... In the next version I can restore the transferring way like in version 6.1... P.S. I also don't understand why you have problem only with this file "N9_QuickTweak_ru_v6.2.pdf", that mean a problem not in the transferring way :-/
