Step 1. Install Akamai Download Manager

In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below is a list of programs that support the file DLM.

Step 2. Create association of Akamai Download Manager with DLM files

If, despite the installed application, the DLM file does not start in the Akamai Download Manager application, you must create a file association. It is most convenient to call the context menu with the right mouse button and select Properties. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can set the program to handle this type. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. The "always use the selected program ..." field will set the Akamai Download Manager application as the default for handling the DLM file.

Step 3. Update Akamai Download Manager to the latest version

If, however, after binding Akamai Download Manager with Akamai Download Manager Format there were still problems, you should update the program to the latest version. In this case, use the Akamai Technologies website or update the program from the application.

Step 4. Check for the following problems with the DLM file

Of course, it may happen that despite the above steps, the file still does not work. The most common file problems are:

Very often, the file may be size 0 or incomplete. This suggests truncating the DLM file contents when downloading or copying. The only repair option is to download the file again.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. If this is not possible, you can use the online scanner. However, it is important to scan the entire system, not only the file DLM or the program directory. Sometimes virus-infected DLM files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the DLM files changes over time. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
The file may be corrupted in a number of ways. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular DLM file corruption. You can restore the file from a backup or use Akamai help.
The program indicates that the file is encrypted or corrupted. The encrypted DLM files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. While there is usually no problem reading such a file, it may not be possible to save it. It is best to move DLM to a different directory.
This problem usually affects more complex files. In this case, the DLM file is blocked by the first application to open it. Just close unnecessary programs. Sometimes you have to wait for the session to the file DLM to close. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If this does not work either, restart the device.
