How to open P7B file?

The most common problem when using PKCS #7 Certificate Format is that a specific P7B is not associated with the program. Thus, when you open P7B, 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 P7B 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 Adobe Reader

In this case, you should first verify that the Adobe Reader application is installed on the computer. The easiest method is to use the system search engine by entering the program name Adobe Reader in it. If we do not have this program, it is worth installing it, as it will help you automatically associate the file P7B with Adobe Reader. Later in this article you will find a list of programs that can open P7B files.

Step 2. Create association of Adobe Reader with P7B files

However, it may happen that the application itself does not cause the P7B file to open in the Adobe Reader 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. Changes can be made using the "Change" button. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. The "always use the selected program ..." field will set the Adobe Reader application as the default for handling the P7B file.

Step 3. Update Adobe Reader to the latest version

If, despite the association of the Adobe Reader program with the PKCS #7 Certificate Format file, the file still does not open, check the program version and possibly update it to the newest version. This can be done using the application (if it provides such options) or from the Adobe Systems Incorporated website and install the latest version.

Step 4. Check for the following problems with the P7B 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 affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the P7B 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. For the best results, we will scan the entire operating system, not just our P7B file. Sometimes virus-infected P7B files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the P7B 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.
The file may be corrupted in a number of ways. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular P7B file corruption. You can restore the file from a backup or use N/A help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted P7B files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. It is best to move P7B to a different directory.
This can happen on a file that does not support multiple access. In this case, the P7B 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 P7B file again. However, some background programs may block the P7B file while scanning. If nothing helps, please reset the device.
