Olympus Pen Lite E-PL7 camera is supported in Lightroom 5.7.1 so, you should be able to import the raw images directly.
Could you please confirm if you receive any error message at the time of import?
If possible, share a screenshot with the exact message.
Dear Ms. Chetna Srivasta,
Many thanks for the prompt reply. Attached is the screen-shot. You will see that the preview is not available.
Could it be some inherent defect in the camera? It is unlikely as Olympus E-PL7 RAW files can be opened in other imaging processors, e.g., Paint Shop Pro X8, DXO OptiPro10, etc.
With regards. Dr. A. K. Kundu.
