This issue can be addressed by downloading and installing OpenSSL or different compatible program, such as Apple Keychain Access. The full list of programs grouped by operating systems can be found above. One of the most risk-free method of downloading software is using links provided by official distributors. Visit OpenSSL website and download the installer.

Step 2. Update OpenSSL to the latest version

If the problems with opening P7 files still occur even after installing OpenSSL, it is possible that you have an outdated version of the software. Check the developer’s website whether a newer version of OpenSSL is available. Sometimes software developers introduce new formats in place of that already supports along with newer versions of their applications. If you have an older version of OpenSSL installed, it may not support P7 format. The most recent version of OpenSSL is backward compatible and can handle file formats supported by older versions of the software.

3. Verify whether your account has administrative rights

There is a possibility that the file in question can only be accessed by users with sufficient system privileges. Log out of your current account and log in to an account with sufficient access privileges. Then open the PKCS #7 Digital Certificate Format file.

4. Make sure that the system has sufficient resources to run OpenSSL

If the system is under havy load, it may not be able to handle the program that you use to open files with P7 extension. In this case close the other applications.

5. Verify that your operating system and drivers are up to date

Up-to-date system and drivers not only makes your computer more secure, but also may solve problems with PKCS #7 Digital Certificate Format file. Outdated drivers or software may have caused the inability to use a peripheral device needed to handle P7 files.
