How do I make adobe digital editions my default

[RogerOsborn]

I assume you have ADE installed on your computer.  You need to "associate" acsm files with ADE.

In Windows 7 :  Click Start, then Default Programs, then associate a file type or program, then set acsm to ADE.  For other Operating systems google associate and the OS.
