How to open SLF file?

An often recurring problem with Symantec License Format is that SLF is not associated with the correct program file. Thus, when you open SLF, the program selection wizard or some other program starts. How to solve such a problem?

The first thing you should do is just "doubleclick" on the SLF 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 Symantec AntiVirus

In this case, you should first verify that the Symantec AntiVirus application is installed on the computer. To do this, enter the name Symantec AntiVirus into the system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file SLF with Symantec AntiVirus. Later in this article you will find a list of programs that can open SLF files.

Step 2. Create association of Symantec AntiVirus with SLF files

However, it may happen that the application itself does not cause the SLF file to open in the Symantec AntiVirus 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 displayed window will contain information about the program that supports this type of file. Using the "Change" button we can set the program to handle this type. 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. The "always use the selected program ..." field will set the Symantec AntiVirus application as the default for handling the SLF file.

Step 3. Update Symantec AntiVirus to the latest version

The fault may also lie with the Symantec AntiVirus program, it is possible that Symantec License Format requires a newer version of the program.

Step 4. Check for the following problems with the SLF 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. This suggests truncating the SLF file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
The computer may have fallen victim to a computer virus or hacker. Perform a virus scan using available and up-to-date anti-virus software. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the SLF file that we want to open. Sometimes virus-infected SLF files cannot be recovered, so make a backup in advance.
Older version of SLF 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. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular SLF file corruption.
The program can also signal the fact of encryption. The encrypted SLF 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. These directories are write-protected to them and it's very hard to fix this problem. If possible, you can try to move the SLF file to another location.
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 SLF file again. However, some background programs may block the SLF file while scanning. If this does not work either, restart the device.
