What is CERT file?

The file in the CERT format belongs to the Web Files category. It was designed by AOL Inc.. Web Files consists of 303 similar files. Netscape Certificate Index is supported by 1 operating systems.

How to open CERT file?

The main problem with Netscape Certificate Index is that the CERT file is incorrectly associated with programs. This is manifested by the fact that CERT 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 CERT 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 Netscape Navigator

The first step is to check if the computer has the Netscape Navigator program installed. To do this, enter the name Netscape Navigator into the system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below is a list of programs that support the file CERT.

Programs to open CERT file

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

Step 2. Create association of Netscape Navigator with CERT files

However, it may happen that the application itself does not cause the CERT file to open in the Netscape Navigator 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 select the desired program. 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 Netscape Navigator application as the default for handling the CERT file.

Step 3. Update Netscape Navigator to the latest version

If, however, after binding Netscape Navigator with Netscape Certificate Index there were still problems, you should update the program to the latest version. This can be done using the application (if it provides such options) or from the AOL Inc. website and install the latest version.

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

If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:

The CERT file may be unusually small compared to the original file. Usually this applies to CERT 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 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 CERT or the program directory. As a result of the scan, sometimes it is not possible to recover CERT files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
A typical compatibility error - the program does not support the older version of the CERT file. 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 CERT files. You can restore the file from a backup or use AOL Inc. help.
The program can also signal the fact of encryption. The encrypted file CERT except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
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. Copying the CERT file to another location will fix the problem.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. Sometimes it is necessary to wait a while before referencing the CERT file again. 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.
