Sometimes it happens that despite having the right application and the correct configuration, there are still problems with opening the 7Z files. Check out other possible problems related to 7Z files. Remember! Manually editing the system registry is only recommended for advanced users, and changes made to it without proper knowledge may result in damage to the system. Finally, select the 'Always use the selected program to open 7Z files' option and confirm the whole operation.Click 'Find more applications on this PC' and indicate the installation location of the appropriate program.Right click on the unknown 7Z file you want to open.The second way is simpler and definitely recommended for less advanced users.
This can be done in two ways - one is to manually edit the Windows Registry and HKEY_CLASSES_ROOT keys. If the user already has one of the applications installed, the next step will be to associate it with the file extension 7Z. Associate WinZip with the 7Z file extension
