What is PEF file?

This file has a binary format.  A file that has a .PEF extension is a Pentax Raw Image file, and PEF stands for Pentax Electronic File.
The Pentax Electronic File is an unedited or an uncompressed photo taken using a Pentax camera. Since the image is yet to undergo any form of processing, this file extension is a representation of all the raw data collected by the camera’s sensor, with no color adjustments.
Note that not all Pentax camera models store images in the PEF format, and so, some software programs will read some, but not all the PEF files.

What else may cause problems?

There can be more reasons which determine that you are not able to open the PEF file (apart from the lack of the proper application installed).

First - the PEF file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the PEF file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the PEF file should be solved.

Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the PEF file has not been completed and it cannot be opened properly).
