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 File -> Download/Install Resources… menu. You will find the downloaded resources stored in .p8z files that are found in the _Resources directory in \My Paratext 8 Projects. (Paratext 9 enhanced resources are stored as .mbv1z files).
