The first thing you should do is just "doubleclick" on the SUM file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.
Step 1. Install Garmin Connect
The first step is to check if the computer has the Garmin Connect program installed. The easiest method is to use the system search engine by entering the program name Garmin Connect in it. 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 SUM.

Step 2. Create association of Garmin Connect with SUM files
If, despite the installed application, the SUM file does not start in the Garmin Connect 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 select the desired program. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. Checking the "Always use the selected program ..." box will permanently associate the SUM file with the Garmin Connect program.
Step 3. Update Garmin Connect to the latest version
If, however, after binding Garmin Connect with Garmin Checksum Format there were still problems, you should update the program to the latest version. In this case, use the Garmin Ltd. website or update the program from the application.
Step 4. Check for the following problems with the SUM 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 suggests truncating the SUM file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. 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. For the best results, we will scan the entire operating system, not just our SUM file. Sometimes virus-infected SUM files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the SUM file. 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 the failure. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the ability to automatically repair SUM file corruption. You can restore the file from a backup or use Garmin help.
The program indicates that the file is encrypted or corrupted. The encrypted SUM 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. The problem is only writing to the file, not reading it. Copying the SUM file to another location will fix the problem.
This problem only occurs with more complex files. 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 SUM file again. Some anti-virus or backup software may occupy the SUM file for a certain period of time. If the problem persists, restart the machine.
