How to open RGN file?

The most common problem when using Garmin Regional Map Format is that a specific RGN is not associated with the program. This causes the file RGN to open by system applications not designed for this purpose, or to display a message that there is no associated program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the RGN 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 MapInstall

In this case, you should first verify that the Garmin MapInstall application is installed on the computer. The easiest method is to use the system search engine by entering the program name Garmin MapInstall in it. If we do not have this program, it is worth installing it, as it will help you automatically associate the file RGN with Garmin MapInstall. Below is a list of programs that support the file RGN.

Programs to open RGN file

Remember to download programs supporting RGN files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Garmin MapInstall with RGN files

If, despite the installed application, the RGN file does not start in the Garmin MapInstall application, you must create a file association. 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. 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 Garmin MapInstall application as the default for handling the RGN file.

Step 3. Update Garmin MapInstall to the latest version

If, despite the association of the Garmin MapInstall program with the Garmin Regional Map Format file, the file still does not open, check the program version and possibly update it to the newest version.

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

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

The affected file may be 0 KB or smaller than expected. This suggests truncating the RGN file contents when downloading or copying. Downloading the file again should fix the problem.
The most common cause here is computer viruses. A virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file RGN or the program directory. However, remember that not every infected RGN file can be recovered, so it is important to take care of regular backups.
Older version of RGN file may not always be supported by the latest software version. Help should be sought from the software developer, as they usually recommend using free file converters or installing 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 option of recovering data from damaged RGN files.
When reading, a message appears that the file was encrypted or corrupted. The encrypted RGN files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. These directories are write-protected to them and it's very hard to fix this problem. It is best to move RGN to a different directory.
This problem only occurs with more complex files. Some file types can only be opened in one program at a time. Closing other programs should help. Sometimes you have to wait for the session to the file RGN to close. Some anti-virus or backup software may occupy the RGN file for a certain period of time. If the problem persists, restart the machine.
