Step 2. Create association of AirMap with AT5 files

However, it may happen that the application itself does not cause the AT5 file to open in the AirMap application, but you can set it manually. This option is available from the level of Properties of a specific file available in the context menu. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Changes can be made using the "Change" button. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the AT5 file with the AirMap application.

The fault may also lie with the AirMap program, it is possible that Lowrance Map Format requires a newer version of the program.

Step 4. Check for the following problems with the AT5 file

The problem may also be with the file itself if the above steps don't work. This could be due to the file itself, the cleanest issues are:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the AT5 file. The only repair option is to download the file again.
The operating system may be infected with a computer virus. A virus scan using an up-to-date antivirus program should fix the problem. If this is not possible, you can use the online scanner. However, it is important to scan the entire system, not only the file AT5 or the program directory. Sometimes virus-infected AT5 files cannot be recovered, so make a backup in advance.
Older version of AT5 file may not always be supported by the latest software version. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for this. Repairing is very dependent on the file type. Some programs offer the option of recovering data from damaged AT5 files.
When reading, a message appears that the file was encrypted or corrupted. The encrypted AT5 files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some of the system directories are excluded from modification. The problem is only writing to the file, not reading it. If possible, you can try to move the AT5 file to another location.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the AT5 file again. Some anti-virus or backup software may occupy the AT5 file for a certain period of time. If the problem persists, restart the machine.
