I followed all the instructions on my QNAP TS-253 Pro, with QTS 4.2.3,set all the permissions to run by admin and the result that Xeams failed to start and the wrapper.log reports 

jre/bin/java: error while loading shared libraries: libdl.so.2: wrong ELF class: ELFCLASS32

IS this the mix with the OS supporting libraries or what else ...

Please advice.
