When running tool from source, i see the bug: "Errno 13: Permission denied: '~/wisecreator/venv/lib/python3.8/site-packages/wisecreator/third_party/mobitool-linux-i386" due to lacking execute permission of mobitool-linux package. Then i add the permission and everything is okay
Also i matched mobitool path correctly to OS architecture. 32bit use i386 and 64bit use x86_64 package
