Yes. To obtain resource files for offline installation, you will need to copy them from a computer that has already downloaded them in Paratext using the Download/Install Resources… option on the File menu (Paratext 8) or Paratext menu (Paratext 9). You will find the downloaded resources stored in the _Resources directory in \My Paratext 8 (or 9) Projects. Copy all the files in that directory to a flash drive. Put that flash drive in the target computer and you can now install them in Paratext on any computer from the Download/Install Resources… menu.
