The files with .ACSM extension are small files that are created and also employed when a person downloads an electronic book from Adobe. The files with this extension generally contain a unique activation ID but not contain the eBook itself. When a person intends to download an EBook, his/her request is sent to an Adobe Content Server. The requested book gets encrypted and then sent to the person, who placed the order for the book. This is an automated process that makes sure that only the person to whom the book is intended gets the chance to open the book.
When you install one of the applications from the list of programs that you found here, you should be able to open or edit the file with the ACSM extension without any issue. However, if you still have problems with this, you may use the option of ACSM file conversion to a different format.

There can be more reasons which determine that you are not able to open the ACSM file (apart from the lack of the proper application installed).
First - the ACSM 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 ACSM 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 ACSM 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 ACSM file has not been completed and it cannot be opened properly).
