I'm new to this, but I've followed all the instruction to install this app on my TS-412. 1) I've tried to install the app from the Store, however once I enter the account details I get the error "Web Page Not Available", So I've un-installed and removed the BitTorrentSync folder from the .qpkg folder. 2) I've tried to follow the instructions on this site to do it manually, however when I try to run the ./make.sh I get the error "qbuild is required......" The saw this on the forum and tried the symlink but I then get an error of "ln: /bin/bash: File Exists" 3) Now tried to download the arm version from the BTSync site and it won't install under a manual, even after un-tar. My QNAP has been recently rebuilt with firmware 4.1.0. Any ideas or help would be appreciated..
