Quite often, when updating the system components of Windows systems, when installing or uninstalling some specific programs and updating them, you may encounter a message with the code 0x80070643 "An unrecoverable error has occurred during the installation." Failure is not critical in principle, nevertheless it is very annoying, and the computer system begins to freeze, slow down, some applications refuse to work, and so on. Hereinafter, several basic methods will be given to correct this situation. In any case, at least one of them will help to fix the problem.
What does the message with the code 0x80070643 mean “During the installation, an fatal error occurred”?
Almost all experts note that this situation is associated exclusively with one component of the system - the Microsoft .NET Framework.
This also applies to its incorrect installation, and automatic updates. It is because of it that a failure occurs with the code 0x80070643 "An unrecoverable error occurred during the installation." It would seem that the easiest and most logical solution is to reinstall. Not. It's not so simple. The problem may also lie in programs that use this platform in the process.
Failure 0x80070643 "Fatal error occurred during installation" Intel Driver Utility
One of the most common problems is installing a utility for updating Intel drivers. Accordingly, the devices of this manufacturer in the corresponding dispatcher are marked as unknown, and the automatic installation of drivers from the database of the system does not give a result. In this case, it is impossible to install even drivers downloaded from the manufacturer’s official website.
To solve the problem, you can apply a universal solution, which is useful in some other cases. We use the services section, which you need to enter through the services.msc command in the Run console, where we look for the system installer service (Windows Installer). Double-click on the line with the name of the component and set the manual start in the startup type, and then start the service. After that, you can install this software or check for updates on the official developer resource on the Internet.
Basic troubleshooting technique
However, there are simpler general solutions. Now a few more examples of a failure with the code 0x80070643 "An unrecoverable error occurred during the installation." Viber can also display this message when uninstalling. Deleting a program becomes impossible even when using narrowly targeted programs. Another situation of the manifestation of the failure 0x80070643 “An unrecoverable error occurred during the installation”: XPERIA (Sony series of smartphones) also displays a similar message when updating.
As already mentioned, it will be necessary to correct the situation with the above platform. To begin with, it is recommended to roll back the system to the state that preceded the failure, and then in the “Update Center” start the update search in manual mode, if this does not happen automatically. When they are found, they will only have to integrate into the system.
If the error 0x80070643 “An unrecoverable error occurred during the installation” occurs, you can do otherwise by manually deleting the platform. There are two ways.
In the first case, you need to use the programs and components section, where you should find the line with the name of the platform and use the delete. In a new window, a check mark is placed in front of the restore point (and not the deletion point), after which it remains only to wait for the process to finish and completely reboot the system.
In the second option, you can remove the platform completely. But it’s advisable to use not a standard partition, but applications like iObit Uninstaller. After all the files and registry keys are deleted, you need to restart your computer or laptop, and then use the update in the "Update Center" or download the latest version of the installation distribution package from the Microsoft website (Downloads section) and install the platform yourself.
It is very simple to integrate the platform into the system, since the installer himself involves launching an automated “Wizard”, and during the installation process, the user only needs to follow his instructions. The same, incidentally, applies to the recovery process. The only and main condition is a complete reboot upon completion of the process.
Conclusion
It remains to add that the above method in most cases is very effective. Of course, if all else fails, you can turn to a specialized recovery utility for the platform itself, which, again, can be downloaded completely free from the Microsoft website.
Sometimes some users try to use programs like Fix It! and DLL Suite. In principle, there is nothing wrong with this, however, they are not specifically designed to restore the Framework, although they can fix some problems associated with the platform.
It did not address the problems associated with exposure to viruses or the presence of errors on the system disk. Check in these two areas before making a decision to correct the failure must be mandatory. Perhaps, additional measures will not have to be taken.
Finally, one more instruction can be given. In principle, it is better to perform all of the above operations when booting the system in safe mode. It is believed that this is more reliable. The mode itself is designed specifically for use in the event of any malfunctions or malfunctions in the system. This applies, by the way, to troubleshooting problems with the platform, and checking for viruses or for fatal errors in the system partition.
Please note that everything can be in order with the platform, and the problem itself may consist in the operation of the update installation center. If this is true, then it will be necessary to eliminate his mistakes. But this is a separate issue.
