What does the error message "could not open 'URRLLink .ascm" mean?


If you see an error message that looks something like "Adobe Acrobat Reader DC could not open 'URRLLink .ascm' because it is either not a supported file type or because the file has been damaged", it is likely you need to change the default program that opens an ACSM file. This document explains how to change the default program using Windows 10, Windows 7 or Mac. In these examples, the default program used is Adobe Digital Editions, but these steps will also work for Bluefire Reader or other software.
