How to open FNX file?

The most common problem when using Fenix Key is that a specific FNX is not associated with the program. Thus, when you open FNX, the program selection wizard or some other program starts. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the FNX 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 Fenix Key

In this case, you should first verify that the Fenix Key application is installed on the computer. To do this, enter the name Fenix Key into the system search engine.

Programs to open FNX file

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

Step 2. Create association of Fenix Key with FNX files

If, despite the installed application, the FNX file does not start in the Fenix Key application, you must create a file association. It is most convenient to call the context menu with the right mouse button and select Properties. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can select the desired program. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the FNX file with the Fenix Key application.

Step 3. Update Fenix Key to the latest version

The fault may also lie with the Fenix Key program, it is possible that Fenix Key requires a newer version of the program. This can be done using the application (if it provides such options) or from the Lavarow Team website and install the latest version.

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

The problem may also be with the file itself if the above steps don't work. The most common file problems are:

The affected file may be 0 KB or smaller than expected. Usually this applies to FNX files downloaded from the Internet in case the download did not finish properly. 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. However, it is important to scan the entire system, not only the file FNX or the program directory. However, remember that not every infected FNX file can be recovered, so it is important to take care of regular backups.
This can happen especially when the program is dynamically developed and the structure of the FNX files changes over time. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for the failure. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular FNX file corruption. You can restore the file from a backup or use Lavarow Team help.
The program indicates that the file is encrypted or corrupted. The encrypted FNX 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 operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. The problem is only writing to the file, not reading it. It is best to move FNX to a different directory.
This can happen on a file that does not support multiple access. In this case, the FNX file is blocked by the first application to open it. Running programs (including those in the background) should be verified. Sometimes it is necessary to wait a while before referencing the FNX file again. However, some background programs may block the FNX file while scanning. If this does not work either, restart the device.
