How to open DLB file?

The most common problem when using Troj/Dloadr-AHT is that a specific DLB is not associated with the program. This is manifested by the fact that DLB files open in unusual applications or do not have an assigned program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the DLB 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 BitDefender

In this case, you should first verify that the BitDefender application is installed on the computer. To do this, enter the name BitDefender into the 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 DLB files.

Step 2. Create association of BitDefender with DLB files

However, it may happen that the application itself does not cause the DLB file to open in the BitDefender application, but you can set it manually. 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. Changes can be made using the "Change" button. 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. The "always use the selected program ..." field will set the BitDefender application as the default for handling the DLB file.

Step 3. Update BitDefender to the latest version

If, however, after binding BitDefender with Troj/Dloadr-AHT there were still problems, you should update the program to the latest version. In this case, use the Softwin website or update the program from the application.

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

Of course, it may happen that despite the above steps, the file still does not 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 is most often caused by a problem while downloading the DLB file. 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. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file DLB or the program directory. As a result of the scan, sometimes it is not possible to recover DLB files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
This can happen especially when the program is dynamically developed and the structure of the DLB files changes over time. 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 this. Repairing is very dependent on the file type. Some programs offer the option of recovering data from damaged DLB files. The easiest way is to restore the file from a backup, if there is one, or contact N/A
The program can also signal the fact of encryption. The encrypted DLB 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 of the system directories are excluded from modification. The problem is only writing to the file, not reading it. If possible, you can try to move the DLB file to another location.
This can happen on a file that does not support multiple access. In this case, the DLB file is blocked by the first application to open it. Closing other programs should help. Sometimes you have to wait for the session to the file DLB to close. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If the problem persists, restart the machine.
