The main program that supports this format is ENVI. This was created by Exelis Visual Information Solutions.
How to open KER file?
The main problem with ENVI Filter Kernels is that the KER file is incorrectly associated with programs. Thus, when you open KER, 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 KER 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 ENVI
The first step is to check if the computer has the ENVI program installed. This can be achieved by typing ENVI into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support KER files.
Programs to open KER file
Remember to download programs supporting KER files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of ENVI with KER files
If the application is or has been freshly installed, but the KER file still does not use the ENVI program, it means no 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. 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. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the KER file with the ENVI application.
Step 3. Update ENVI to the latest version
If, however, after binding ENVI with ENVI Filter Kernels there were still problems, you should update the program to the latest version. In this case, use the Exelis Visual Information Solutions website or update the program from the application.
Step 4. Check for the following problems with the KER file
The problem may also be with the file itself if the above steps don't work. The most common file problems are:
Very often, the file may be size 0 or incomplete. Usually this applies to KER files downloaded from the Internet in case the download did not finish properly. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file KER or the program directory. Sometimes virus-infected KER 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 KER files changes over time. 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. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the option of recovering data from damaged KER files. The easiest way to restore the file is from a backup or by contacting Exelis Visual Information Solutions, but this one can be expensive. Not all damage can be reversed.
The program indicates that the file is encrypted or corrupted. The encrypted KER 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.
Some of the system directories are excluded from modification. These directories are write-protected to them and it's very hard to fix this problem. It is best to move KER to a different directory.
This problem only occurs with more complex files. In this case, the KER file is blocked by the first application to open it. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the KER file again. However, some background programs may block the KER file while scanning. If nothing helps, please reset the device.
