Both of those modules are topic modules that are in topx file format the reason for this that e-Sword is programmed to recognize only certain books of the Apocrypha.
The module for the Book of Jasher is an exe file this means that once the file is downloaded you must run the exe file to install the module. The Book of Jubilees is a topx file that can be downloaded and then pasted into your e-Sword folder.
So i have to rename the jasher file to exe ?
So the Jubilee file just copy and paste it to esword folder ?
